Jeremy Corbyn's team are facing fresh accusations that they obstructed Labour's campaign to keep Britain in the EU after BuzzFeed News obtained another set of leaked emails revealing disagreements between Remain campaigners and Corbyn's head of strategy, Seumas Milne.

The leaked email threads – reproduced in full below – will add to criticism that the Labour leader's office was reluctant to offer a positive case for EU membership.

One email exchange took place on 18 May, just over a month before the vote. In it, a senior figure from Labour In for Britain, the party's pro-Europe campaign, took Milne to task for failing to include lines about the EU in a Corbyn speech draft that was being briefed out to the media.
