SWANSEA: Gower MP Tonia Antoniazzi calls on Keir Starmer to step aside — as Swansea East’s Carolyn Harris backs him to stay
Gower MP Tonia Antoniazzi has become one of dozens of Labour MPs calling on Keir Starmer to step down as Prime Minister — warning that the party now faces “the real possibility of a Reform administration” if it does not change course.
In a statement posted to social media, Antoniazzi acknowledged Starmer’s integrity and his record on international issues, including keeping Britain out of the conflict between the United States and Iran. But she said the election results had made clear he had lost the confidence of the country.
“The pace of change is not being felt quickly enough by the people of Gower,” she said. “Recent election results make clear that the Prime Minister has lost the confidence of the country. Too much of our good work has been lost because we have not explained our policies clearly or brought people with us. When people do not understand what we are doing or why, they lose trust, and that trust is hard to rebuild.”
She warned that Reform’s rise posed a genuine threat that the current leadership could not meet. “We now face the real possibility of a Reform administration, a party that promotes Trump-style populism and exploits discontented people but is really about benefiting its wealthy backers. We need a Labour Party and a Government that are strong enough to stand up to that threat with delivery. I do not believe that Keir can lead that fight.”
She concluded: “For the sake of my constituents, for the Labour movement, and for the country, it is time for new leadership.”
The intervention puts Antoniazzi at direct odds with Swansea East MP Carolyn Harris, who posted a public statement backing the Prime Minister to continue in the role. Harris argued that a leadership contest would be “a distraction at a time when the country is facing serious challenges at home and abroad” and pointed to the government’s record on NHS waiting lists, workers’ rights and housing.
“This Government has already delivered real progress: NHS waiting lists have fallen for eight months in a row, workers’ rights have been strengthened, renters have been given greater security,” Harris said. “Keir Starmer should be given the opportunity to deliver the change we promised and get on with the job.”
The two local MPs find themselves on different sides of a rebellion that had grown to 85 Labour MPs by Tuesday morning, rising steadily since the party’s dismal performance in elections across the UK last week.
Labour suffered heavily across the board — losing control of more than 30 councils in England and around 1,500 councillors, while in Wales it was reduced to just nine Senedd seats, with First Minister Eluned Morgan losing her own seat. The scale of the collapse in Wales was particularly damaging for Starmer, with pollster Sir John Curtice having warned before the election that losing Wales would pose a greater threat to his leadership than any other result.
Starmer addressed the Parliamentary Labour Party on Tuesday in a speech that was greeted with a fresh wave of demands to step aside. He vowed not to “walk away” from Downing Street, saying: “This is nothing less than a battle for the soul of our nation.”
His speech was dismissed as “utterly inadequate” by one former minister, while ministerial aides to three cabinet ministers — including aides to the health secretary, home secretary and environment secretary — resigned their roles in protest.
Sharon Graham, general secretary of Labour-backing union Unite, said Starmer’s speech had not “cut the mustard”, adding: “There isn’t a cat in hell’s chance that Keir Starmer’s going to lead us into the next election. It would be the death knell if that happened.”
Antoniazzi, who has represented Gower since 2017 and is a former Wales women’s rugby international, has a history of independent thinking within the party, having previously resigned as a Labour PPS in protest at the Brexit trade deal vote. She was born and raised in Llanelli and has been a vocal constituency voice throughout her time in Westminster.
Harris, who has served as MP for Swansea East since 2015, is one of the most prominent Welsh Labour voices in Westminster, having served as a minister in the Welsh Office and as a shadow minister on gambling reform.
Starmer has so far refused to announce a departure timeline, insisting he will not walk away. Whether that position is sustainable as the parliamentary rebellion continues to grow will become clearer in the days ahead.
