The MP for Morecambe and Lunesdale has given her response after Sir Keir Starmer announced his resignation as Prime Minister.
Lizzi Collinge was speaking after the PM announced on Monday morning his decision to step aside.
"I think the Prime Minister has made the right decision, and done so with grace," she posted on her Facebook page.
"I will always be grateful for everything he has done for the party and for the country."
In a statement outside 10 Downing Street, Starmer said his party had been asking whether he's "best placed to lead us into the next general election" and said "I have heard the answer"
He said that every decision he had made in office had been about "putting the country I love first" and, visibly emotional, thanked his "fantastic wife, Vic" and said he wants to be "the best dad I can be to my beautiful children".
The PM said he'd remain in post until Labour selects a new leader, which he said he'd asked to happen before Parliament returns in September.
Andy Burnham, who won a by-election last week to become MP for Makerfield, has become a leading contender to take over as Labour leader and Prime Minister.
In May, Ms Collinge was one of a number of MPs who called for the Prime Minister to step down, after poor local election results for Labour, part of a remarkable fall in popularity for the party since its landslide General Election victory in 2024.

"I have been taking time over the past week to reflect on the local election results elsewhere in the country, to reflect on our first two years in Government, and of course to speak with my constituents," said Ms Collinge in May.
"I am immensely proud of the progressive and important legislation we have passed, from the Employment Rights Act to the Water (Special Measures) Act.
"I am also proud of the clear and concerted action we have taken on the most pressing issues of our time: economic stability, clean energy and climate change, national security, and improving the NHS.
"We had a very difficult inheritance from 14 years of destructive Conservative government, and any Prime Minister would have struggled to solve the problems our country faces in two years.
"I also recognise that the Prime Minister has led us through some extremely difficult international situations with skill and I thank him for that.
"However, it is clear to me that the Prime Minister has now lost the confidence of the country. And as an MP, my first duty is to my constituents and to my country. It is for this reason that I am now calling on the Prime Minister to step back and arrange an orderly transition to new leadership.
"I believe that Labour values and policies are still the only way to improve our country and we need a Prime Minister who can show the country what progress we have made and can still make.
"Labour don’t offer simplistic slogans, we offer real solutions. Governing a country requires compromise and hard choices, and we're the only party who faces up to that.
"We also face some opposition that simply operates outside the norms of decency and honesty. I have seen this locally and nationally. We need to fight to steer our country away from the terrible future they want, a future riven with division and with policies based on prejudice and ideology, not facts, evidence or positive values.
"I love our country and I love the people in it. I will keep on working to make life better for every person in Morecambe and Lunesdale, and for every person in the UK."
David Morris, Ms Collinge's predecessor as Morecambe and Lunesdale MP, also posted his reaction on Monday to Starmer's resignation.
Mr Morris, a Conservative (below), called it "an inevitable moment of reckoning".
"During my time serving as your veteran MP, we fought hard and delivered great, tangible changes that brought real hope to Morecambe," he said.
"It has been heartbreaking to watch those achievements dismantled and to see our local community pushed back 20 years by a brand of politics that beguiled voters rather than delivering for them.
"Today, the illusion is over. But changing the person at the top of a failing government isn’t enough.
"We need an early General Election now. That is the only way to give the people their voice back, remove this stagnation, and finally restore Morecambe and the surrounding district to the path of growth, pride, and real progress."
