Tube drivers walked out at midnight in a dispute about the introduction of a voluntary four-day working week
Services will be disrupted throughout the day with no trains running on some lines, and delays and part suspensions on others
TfL is proposing a 35-hour, four-day week for Tube drivers, but the RMT union has called for this to be reduced to 32 hours across four days for drivers' safety - it's tricky to see how the dispute will be resolved, BBC London's transport correspondent writes
Business owners fear "there's going to be no one in London", as commuters describe long queues to take multiple buses into work
Buses, London Overground, DLR and tram services are running, and there's good service on the Elizabeth Line after earlier delays due to a points failure

It's more misery for commuters travelling on the Northern line, which is now part suspended between Golders Green and Battersea Power Station.
TfL says it's due to strike action.
There are also severe delays on the rest of the line, with services operating every 15 minutes.
Elsewhere on the Tube, the Jubilee line is running a normal service, while there are minor delays on the Victoria line.
All London Overground lines are now operating a normal service, TfL says.
The Lioness line was part suspended for several hours but services have returned to normal.
The Elizabeth line, which commuters have used as an alternative to the Tube, is also operating as normal.

Rick tells us he was stuck in traffic with his two sons this morning on the way to sit their A-levels and GCSEs.
"My sons made it by the skin of their teeth but anxiety levels were sky high while they were sitting in grid locked traffic," he tells us.
"This is totally disgraceful and I will never forgive the unions if this jeopardises their futures."
Meanwhile, CK, who works as a teacher, was forced to get a cab to Paddington as no drivers were willing to travel to his school in Ealing.
His partner is a nurse and says medical workers like her have been impacted "terribly" by the strikes.
"The number of strikes in the last few months has been absurd," he suggests.
Tom in Islington disagrees. He tells the BBC that Tube drivers have "been clear" about the "immense impact" current working conditions have.
"I have to allow extra time for my journeys today but that’s a reasonable trade-off in my opinion," he says, adding that TfL should agree with the RMT's position and "improve safety for all on the network".
As a reminder, the RMT union is striking after accusing TfL of failing to "provide assurances" over concerns about longer working hours and driver safety. TfL insists "safety is our absolute priority" and says today's strikes are "very disappointing" - more on this in our news story.
The Northern line, which had been running a more regular service, is now experiencing severe delays due to the ongoing strike.
Services are now operating approximately every 15 minutes, TfL says.

The London mayor admits the strikes are "a sign of failure" and urges RMT and TfL to "get round the table" to resolve the issue.
"The workers on strike lose a day's salary, TfL loses revenues, businesses are losing their customers, people have hospital appointments they can't get to. This is a massive inconvenience," he explains.
Pushed on what steps he's taking to prevent a planned second day of industrial action on Thursday, Khan says TfL are "available" today and tomorrow to talk to RMT.
Image source, ReutersToday's Tube strike is the first of two set to disrupt London this week
Today's strike is not the first to hit the capital this year and will be followed by another walkout on Thursday.
The main reason for the strikes in 2026 is the proposed introduction of a 35-hour, four-day week for Tube drivers.

As commuters head for lunch, we're about halfway through the first of two 24 hours walkouts from tube drivers on Tuesday and Thursday.
Here's a reminder of all the warnings issued by Transport for London amid this week's disruption:
There will be no service on the Circle and Piccadilly lines. Trains will be operating on the Metropolitan line between Baker Street and Aldgate and on the Central line between White City and Liverpool Street.
Where services are running, TfL has warned of disruption to journeys, with passengers told to plan ahead and use alternative routes.
Service levels will vary across the tube network and will start late and finish early on Tuesday and Thursday.
It adds there will be limited services before 06:30 and advises customers to finish their journeys before 21:00 on both days.
Meanwhile, there will be normal services across all tube lines on Wednesday 3 June and Friday 5 June, when there are no strikes planned.

Before the disruption, commuters had been able to use the service, which runs from east to west, as an alternative to the Tube as its drivers aren't on strike.
It led to large crowds gathering at an interchange at Liverpool Street station - as our reporter captured in pictures earlier on.
Image source, Getty ImagesLondon Mayor Sadiq Khan is urging the RMT and TfL to find a resolution to the dispute.
“Nobody wants to see strike action - which has a serious impact on Londoners, businesses and commuters," the mayor's spokesperson says.
"The mayor continues to urge the RMT and TfL to get around the table to resolve this matter, so we can avoid further disruption and keep London moving.”
As we reported earlier, RMT union Tube drivers are striking over safety concerns about proposals for a voluntary four-day working week; TfL insists the strike is unhelpful.
Khan is expected to appear live on BBC Radio London shortly after 13:00 BST today to discuss social media policy, and we'll bring you anything he has to say on today's industrial action.
The Lioness line is the latest TfL service to experience delays and is part suspended between Watford Junction and Willesden Junction.
This is due to a faulty train at South Kenton and not a result of the ongoing Tube strike.
Elsewhere, issues on the Mildmay line have now been resolved and the Overground line is operating a good service.

The company's anonymised mobile phone data shows footfall in the City is down 16% compared with a typical Tuesday morning.
Other areas are also seeing lower numbers of people, with Westminster down 11%, King's Cross down 8% and the West End down 6%.
A Virgin Media O2 spokesperson says the figures provide a "real-time snapshot" of how London responds to major transport disruption.

Despite today's walkout by the Rail, Maritime and Transport Workers (RMT) union, three Tube lines are now operating close to normal.
The Northern line is experiencing minor delays, with TfL reporting services every six minutes. This is a longer gap than normal but indicates a regular service.
Similarly, the Victoria line is experiencing minor delays, with services operating every four minutes.
Meanwhile, the Jubilee line is operating a good service with no reported delays.
After earlier severe delays, there are now only minor delays on the Elizabeth line because of an earlier points failure at Slough.
It is worth remembering there is still severe disruption - as well as some suspensions - on the rest of the TfL network.

Reporting from Victoria station
I’ve just spoken to a couple who say they have to hire an Uber, as the taxi line at Victoria station is too long to wait in.
The couple explain that they are heading to their biggest work conference of the year, and seem very anxious about whether they’d make their train.
One of them, a woman, tells me she doesn't think it's "fair" that the public is paying for the dispute between TfL and the RMT union.
“It’s really frustrating and we are cutting it really fine to get our train from Euston to Birmingham," she says.
When strikes took place last month, people were enjoying cycling, walking and other forms of transport because of good weather.
This morning that’s not exactly the feeling as the rain has been pouring and queues for both buses and taxes have been getting longer.
Harry Low
BBC London News
Meanwhile on the taxi rank at King’s Cross, London’s black cabs are doing brisk business.
One of the drivers, Adrian, describes it as a “good day to be a taxi driver especially when the Tubes are gone”.
Another, Paul, says it’s a “pain in the backside”.
He adds: “The traffic’s a nightmare, people get in the cabs who don’t really want to get a cab and people who get cabs moan that they can’t get a cab.
“If they are striking over feeling it’s dangerous to work extra time, I’m in support of it. There are more important things in life than money.”
Commuters are continuing to pour out of King's Cross station, where rain showers have been adding to the misery of a disrupted commute this morning.
It's a similar sight across much of the capital, with thundery showers and a gentle breeze expected throughout the day, despite cool temperatures of around 18C.

Suspended and part suspended
The Bakerloo, Piccadilly and Central lines are part suspended, while the Circle and Waterloo & City lines are suspended entirely.
Severe delays
There are severe delays on the District, Hammersmith & City, and Victoria lines, as well as on the Bakerloo line.
There are also severe delays on Mildmay, which runs on the London Overground, and the Elizabeth line. These issues are separate from the ongoing Tube strike.
Minor delays
There are minor delays on the Northern line, with services operating approximately every six minutes.
Good service
The only Tube line operating a good service is the Jubilee, with no issues reported. The rest of the Overground and DLR are also operating a normal service.
