Newspaper headlines: 'Hours from a no deal' and Tory grandee 'fury'

The lead in the Sunday Times says "ministers warn supermarkets to stockpile food". It says food producers believe that leaving the EU without a trade deal will lead to a three-month shortage of vegetables. An unnamed consultant to one of the supermarket chains tells the paper: "Ministers are hugely worried about panic buying. They saw what happened over Covid, and know how quickly it can go wrong".

Under the headline: "They think it's all Dover", the Sun on Sunday explains that many of the government's contingency plans focus on the port where most lorries arrive from the EU. The measures include hiring up to 900 extra border staff, and bringing hundreds of extra police officers to Kent from other areas. The paper's leader states: "Nobody denies that a no-deal Brexit will initially be bumpy for Britain's economy - but the ultimate financial cost of accepting the EU's disgracefully one-sided deal would be far greater."

"Tory grandees' fury over PM's nationalist no-deal Brexit" is the Observer's lead. It says Boris Johnson is facing a "rising tide of anger" from senior Conservatives. Writing in the paper, the former Tory deputy prime minister Lord Heseltine says he knows cabinet ministers who believe - like he does - that this is "quite simply the worst peacetime decision of modern times". But he adds that he "cannot understand their silence".

The Sunday Telegraph reports that rural parts of England - which had hoped to move to a lower Covid alert level than neighbouring urban areas, with more cases - are likely to be disappointed. It says Boris Johnson had suggested a review of tier allocations - due on Wednesday - would result in local variation, rather than one alert level across whole regions. But the paper says the Health Secretary Matt Hancock has written to Conservative MPs telling them the evidence suggests such a strategy does not work.

According to the Sunday Mirror, British engineers have invented a "miniature Covid-19 vaccine factory" - which can make 30,000 doses of the jab per day. The device - which is about the size of a supermarket trolley - uses computers to mix up the tiny amounts of active substances in each injection. The paper explains that scientists at King's College London came up with it as a possible solution to producing the vaccine in third world countries.

Under the headline "Biden orders exorcism of Trump from White House", the Mail on Sunday reports that the US President-elect has asked that America's most famous residence be deep-cleaned, after Donald Trump leaves in January. A spokesman for Joe Biden's transition team says this is because "Mr Trump's administration has been riddled with coronavirus". The source says a team in protective clothing will go as far as replacing door knobs and removing soft furnishings.

The Sunday Express describes the numbers of Christmas shoppers who ventured out on Saturday as "a boost for town centres". It explains that by midday, cities across the UK had seen an increase of nearly 15% in the number of people shopping - compared to the same period a week earlier. The British Independent Retailers Association is quoted saying the growth is "really encouraging".
