Friday morning news briefing: How Labour anti-Semitism cases 'disappeared'

Corbyn 'complicit' in growing 'tide' of anti-Semitism

It is the dossier that shamed Labour. Jeremy Corbyn has been accused of leading an "institutionally anti-Semitic" party, as a leaked document argued he had been involved in a "cover-up" of the problem. The devastating submission of evidence compares the Labour Party to the Met Police in the Nineties. Political Editor Gordon Rayner examines whistleblower claims that anti-Semitism allegations were made to "disappear" after interventions by Mr  Corbyn. Camilla Tominey explores the extent of the claims, including one from a Labour party conference breakfast at which two delegates "quickly agreed that Jews were 'subhuman' and should 'be grateful we don't make them eat bacon every day'." Here is a reminder of the 15 incidents that claim Mr Corbyn has engaged in anti-Semitic behaviour. And read The Telegraph's view.

Andrew Neil has issued a direct challenge to Boris Johnson to undergo an interview with him ahead of the general election. Addressing the PM on air, the presenter called on him to face questions on why people have "deemed him to be untrustworthy". Meanwhile, Mr Johnson and Mr Corbyn are gearing up for tonight's head-to-head leaders' debate on BBC One. Host Nick Robinson has written for The Telegraph, revealing his sleepless nights - and the advice he was given by David Dimbleby.

Just for Christmas? Plastic warning over jumpers

They may seem like innocent festive fun, but an environmental charity has warned that Christmas jumpers are contributing to the plastic crisis. It says that almost all of the millions of jumpers sold this December are likely to be made with plastic. As Helena Horton reports, they are then only worn a few times before being consigned to the dustbin. Consumers were given advice on what to do instead in order to minimise pollution.
