SIR KEIR STARMER was told today his low popularity will not be salvaged by meaningless relaunches and rebrands as he prepares “a new phase" for his government this week.

The Prime Minister will set out a plan for change with milestones set in key policy areas to achieve the targets laid out in Labour’s manifesto, Downing Street said today.

He will unveil the markers for his “missions” that Number 10 says will allow the public to hold Sir Keir and his team to account on their promises.

The milestones will run alongside public-sector reform and are aimed to be reached by the end of the Parliament.

They will include a focus on reforming Whitehall, spearheaded by the as-yet-unannounced new chief civil servant — the Cabinet Secretary  — and Cabinet ministers.

The targets will also influence decisions for next year’s spending review, it has been suggested.

Labour’s missions, as laid out in its July election manifesto, focus on economic growth, energy security and cleaner energy, the NHS, childcare and education systems and crime and criminal justice.

But it comes as polling for the Observer newspaper by Opinium indicates that more than half of the public disapprove of the PM’s performance.

A spokesperson for Labour’s grassroots group Momentum said: “This announcement only confirms what has long been obvious: Starmer had no vision for the country and no plan to transform the lives of the majority. 

“The two-child cap remains in place, the government has cut winter fuel payments and continues arming Israel. 

“The government’s low popularity will not be corrected through relaunches or rebrands but rather a clear change of direction to implement policies that benefit the many.”
