Angela Eagle has resigned from Jeremy Corbyn's shadow cabinet, becoming the latest in a series of high profile Labour departures in the aftermath of the UK's Brexit decision.
In her resignation letter, Ms Eagle said Mr Corbyn had "lost the confidence of colleagues" and suggested he never had won the confidence of "voters and the wider public".
The shadow Business Secretary became the 15th member of the Labour front benches to step aside after Hillary Benn was sacked in the early hours of Sunday morning.
She was a prominent Remain campaigner - appearing in Mr Corbyn's absence in key TV debates and passionately putting the case for Britain remaining in the EU.
"I was devastated by the result of the EU referendum," she wrote to the party leader. "Too many of our supporters were taken in by right-wing arguments and I believe this happened, in part, because under your leadership the case to remain in the EU was made with half-hearted ambivalene rather than full-throated clarity."
Ms Eagle said she was grateful for the opportunity to serve as Mr Corbyn's shadow Business Secretary and shadow First Secretary.
But she added: "It is with the greatest of sadness that, after nine months of trying to make your leadership work and despite your considerable personal qualites, I have come to the conclusion you are not the right person the lead the party we both love."
