Bermondsey & Old Southwark's Labour MP Neil Coyle has joined the exodus from Jeremy Corbyn's team by quitting as parliamentary private secretary to the shadow leader of the House of Commons.
Coyle was one of the MPs who nominated Jeremy Corbyn for the Labour leadership, ensuring his place on the ballot paper.
Although not a Corbyn supporter, last year he joined the frontbench team on the lowest rung of the shadow ministerial ladder as parliamentary private secretary (PPS) to the shadow leader of the Commons Chris Bryant and his deputy Melanie Onn.
Bryant resigned from the shadow cabinet on Sunday night and Coyle also stepped down as PPS on Monday morning.
In his resignation letter, Coyle warned that the UK's decision to leave the European Union would affect jobs and tourism in Bermondsey & Old Southwark.
He called for Corbyn to the the "decent, dignified and honourable thing" and step down as party leader to trigger a new contest.
