Collymore accuses Twitter of standing by on internet abuse

Former footballer Stan Collymore has accused Twitter of not doing enough to combat abusive messages after he was targeted by internet trolls.

The broadcaster has retweeted some of the offensive messages he has received since he suggested Liverpool striker Luis Suarez dived to earn a penalty in Saturday's match against Aston Villa.

He spoke to Louise Minchin and Bill Turnbull about the abuse.
