Labour MPs will be free to vote for a parliamentary investigation into whether Tony Blair misled the Commons in the run-up to the Iraq war.

Jeremy Corbyn has decided to only impose a one-line whip on his MPs during today's debate. MPs from six parties want a committee to examine the difference in Mr Blair’s evidence to the Chilcot Inquiry and the private assurances he gave to George W Bush in the run up to the Iraq conflict.

A Labour source confirmed to the Telegraph that Mr Corbyn himself will miss the vote this afternoon.
