Labour MP Jess Phillips resigned as a ministerial aide on Monday morning in protest at Jeremy Corbyn's leadership, and appealed to the party leader to "do the right thing".
Phillips, who served as a parliamentary private secretary to the party's education team, told Corbyn: "I'm really worried that you cannot see that you have made this all about you and not about them."
Phillips' resignation came as Corbyn was hit by a fresh wave of resignations on Monday, with shadow ministers telling him that they have no confidence in his ability to lead the party through the Brexit fallout to electoral victory.
"The Labour party is not about you, it's about us, most of all it's about them, the brilliant people in the UK, even the ones who don't agree with us," Phillips wrote in her resignation letter. "We need action, we really needed it last week, the week before.
"I'm really worried that you cannot see that you have made this all about you and not about them. Be the socialist you saw you are, do the right thing and let the Labour party be the opposition it needs to be now, when people need it most."
Phillips also said she risked her job by writing the resignation letter because it's "deeds not words" that matter. BuzzFeed News understands that regional organisers of unions have been calling frontbench MPs and threatening them with deselection if they don't back the party leader.
The Labour MP has received praise for writing her letter to the party leader.

I feel a bit silly writing to resign from my position as the Parliamentary Private Secretary in your shadow education team. It seems a big grand, being as I'm sure most people don't pay the position I had any mind at all, but apparently it is what we do.
I want to thank you for, in the most part responding to me, if I had questions. You haven't had an easy ride, you remained calm throughout.
My main concern is that I'm not sure how good you are at using what people say or need to enact change. I think in this time of huge shifts the opposition myst be at its strongest and its best. Saying stuff won't cut it. We are going to need strong heads, open flexible hearts and detailed forensic wits.
Writing to saying anything against you risks my job, the livelihood of my family, the threats are already rolling in. Turns out when you stand up for what you believe you are principled. When I do it I am an opportunist, careerist Blairite or even a Zionist plotter. Funny that, I am a socialist. I live my life as a socialist. I speak up regardless of the risk because I am considerably less important than the struggle.
I love being the MP in Yardley, never a day goes by when my constituents don't make me smile or make me want to stay up all night fighting their corner. I'd give up tomorrow if I thought my going would rid my constituents of a government that leaves many of them in despair. My mom and dad taught me that socialism isn't words, it's action, deeds not words and all that.
The Labour party is not about you, it's about us, most of all it's about them, the brilliant people in the UK, even the ones who don't agree with us. We need action, we really needed it last week, the week before.
I'm really worried that you cannot see that you have made this all about you and not about them. Be the socialist you saw you are, do the right thing and let the Labour party be the opposition it needs to be now, when people need it most.
All the best, I know none of this has been easy on you and your loves ones. Nobody deserves some for the crap you have put up with. Sorry if I was ever to blame for any upset, perhaps sometimes I took straight talking honest politics a little too literally.
