May 11 (UPI) — British Prime Minister Keir Starmer pledged a bigger, bolder, more optimistic direction for Britain, with a much closer relationship with the European Union at its heart, as he fought to hold onto his job on Monday following a disastrous showing by his party in elections.

In a speech in London, Starmer acknowledged making mistakes, but said he would prove wrong those who doubt his ability to deliver solutions to the country’s problems, saying Labour needed to bring “a bigger response” than they had believed was necessary when they came into office.

“Incremental change won’t cut it on growth, defense, Europe, energy. We need a bigger response than we anticipated in 2024 because these are not ordinary times, and this is a political challenge, just as much as it’s a party challenge,” he said.

While insisting his government had got “the big political choices right” on issues such as not getting involved in the Iran war and “investment in public services,” Starmer promised to do much more on apprenticeships, technical excellence colleges and special educational needs to guarantee a job, training or internship to every young unemployed Briton.

He also promised the most significant overhaul of ties with the EU since Britain officially left the bloc in 2021.

“This Labour government will be defined by rebuilding our relationship with Europe, by having Britain at the heart of Europe, standing shoulder to shoulder with the countries that most share our interests, our values and our enemies. That is the right choice for Britain,” he said.

Taking questions from reporters afterward, he kicked the question of rejoining the EU single market or customs union down the road to beyond the next election — but did not rule either out.

Starmer vowed he would see off any attempt to topple him after Nigel Farage’s Reform UK made historic gains in English council elections and parliamentary elections in Wales and Scotland, at Labour’s expense, and warned those who wanted him out that it could clear the way for Farage.

“We are not just facing dangerous times, but dangerous opponents, very dangerous opponents,” he said, saying Labour was the only thing preventing the country from going down a very dark path.”

“This is nothing less than a battle for the soul of our nation, and I want to be crystal clear about how we will win, because we cannot win as a weaker version of Reform or the Greens. We can only win as a stronger version of Labour, a mainstream party of power, not protest,” Starmer said.

Starmer had faced possible internal party challenges from senior party figures seeking to replace him and wider calls to set a timetable for his departure after the party’s disastrous performance.

However, the BBC said Starmer’s speech appeared to have defused the immediate threat to Starmer of a contest for the leadership of the party — and therefore the prime ministership — with backbench MP Catherine West criticizing his speech as “too little, too late” but backing down from her threat to force a leadership election today.

However, she said she still wanted him gone by September.

“The results last Thursday show that the PM has failed to inspire hope. What is best for the party and country now is for an orderly transition. I am hereby giving notice to No. 10 that I am collecting names of Labour MPs to call on the Prime Minister to set a timetable for the election of a new leader in September,” she wrote in a post on X.

West said she had the backing of 10 of the 81 MPs required under party rules to formally kick off a challenge by an MP. If and once a nomination receives sufficient backing, that would likely trigger a full-blown race for the leadership.

Assuming he does not resign, as sitting prime minister, Starmer is an automatic candidate in any leadership election if he so wishes. Former Labour Party leader Jeremy Corbyn fought and won a contest to remove him in 2016, consolidating his authority, although he was leader of the opposition only and not prime minister.

While Labour leaders have resigned under pressure from the party, the cabinet or the public, none has been removed in a formal leadership challenge in post-war Britain.

West is not seeking to replace Starmer herself.
