Starmer Vows to Investigate Budget Leak Sources

I will get to the bottom of these leaks, says Starmer

The Prime Minister has pledged to thoroughly investigate the origins of damaging leaks concerning the Budget and his Cabinet.

Recently, Chancellor Rachel Reeves informed Members of Parliament that unauthorized pre-Budget disclosures hinted at her abandoning plans to raise income tax rates, prompting an ongoing inquiry.

During discussions with the Liaison Committee, which is composed of chairs from various select committees, Sir Keir Starmer expressed skepticism about the leaks emanating from his own office.

Government Under Scrutiny

MPs directed their inquiries at the Prime Minister, raising concerns regarding standards in public life, particularly whether ministers were adequately held accountable by responding to parliamentary questions.

The government has encountered several embarrassing situations in recent weeks, including allegations of a coup attempt against the leadership by Health Secretary Wes Streeting early in November.

This was soon followed by media reports suggesting a potential reversal on income tax in the upcoming Budget and the unusual early release of the Office for Budget Responsibility’s response to Reeves’ proposals prior to her Commons announcement.

Intolerable Leaks

When questioned about the leaks by Dame Meg Hillier, chair of the Liaison Committee, Sir Keir characterized them as “intolerable,” confirming that an investigation regarding the Budget leaks is underway.

“I have no reason to believe there was a leak from No 10,” Sir Keir asserted.

When asked by Dame Meg if he would consider removing someone found culpable, the Prime Minister affirmed his willingness to take appropriate measures following the investigation’s conclusion.

“I’ll get to the bottom of these leaks; they are intolerable in any organization,” he stated.

Sir Keir noted that he had previously taken similar actions during his tenure as head of the Crown Prosecution Service.

Defending Leadership

The Prime Minister also faced pressure to defend his chief of staff, Morgan McSweeney, after some government figures suggested he was responsible for the negative briefings against Streeting. However, sources indicated that McSweeney would remain in his position.

Addressing the situation, Sir Keir reiterated that any briefings against Cabinet members were completely unacceptable and emphasized that measures had been implemented to address such conduct.

Conservative MP Alberto Costa reiterated his concerns, arguing that leaks from within Number 10 indicated that the Prime Minister had “lost complete control of your Downing Street operation.”

Pressed on his belief that the leaks did not originate from within No 10, the Prime Minister responded, “I received assurances from various levels within Downing Street, from different individuals on my team.”

Assurances and Accountability

When asked whether these assurances came from officials or special advisors, Sir Keir stated, “Special advisors—I’m not naming any staff members, but I didn’t accept everything at face value. I assessed other pieces of evidence to validate my public statements to the media.”
