Jeremy Corbyn. Jeff J Mitchell/Getty LONDON — Jeremy Corbyn faces a fresh wave of resignations from his Shadow Cabinet after signalling that he will order Labour MPs to vote to trigger Article 50 — the process by which Britain leaves the European Union.

The Labour leader confirmed to Sky News that he would expect his MPs to vote for Brexit.

"It will be a clear decision that we want all of our MPs to support the Article 50 when it comes up next week. It is clearly a three line whip," he said.

Under ordinary circumstances any member of the Labour front bench to defy the whip would have to stand down.

Incredibly two of those MPs set to defy the three line whip are still in charge of ensuring Labour MPs follow it.

Thangam Debbonaire, one of Labour's whips, told Business Insider on Thursday afternoon that she will defy the whip if it is imposed and "deal with the consequences". Another Labour whip, Jeff Smith, told the Manchester Evening News that he would also defy the whip.

"My constituents voted strongly for remain and I think it’s important to represent their view,” he said.

Labour's shadow minister for early years, Tulip Siddiq, confirmed to Sky News that she had resigned over the issue.

Several other members of the Shadow Cabinet have also indicated that they are considering voting against the bill.

Labour's shadow Business Secretary Clive Lewis had indicated before that he was considering voting against triggering Article 50, but confirmed on Thursday that he would vote with his party.

"I've been clear throughout that I respect the result of the referendum and will therefore join my colleagues in voting for the bill," he said.

MPs are set to vote on the issue as early as next week following the publication on Thursday of the government's Brexit bill.
