Downing Street was last night facing the threat of a police investigation over claims that the Prime Minister’s chief of staff hid more than £700,000 of donations to boost Keir Starmer‘s political career.
The Tories say they have obtained private legal advice to Morgan McSweeney, Sir Keir’s most powerful aide, which points to a deliberate attempt to mislead the Electoral Commission over money given to Labour Together – the think-tank which played a key role in bringing down Jeremy Corbyn and putting Starmer into power.
The Electoral Commission found more than 20 breaches by the group, and levied a fine of £14,250 in September 2021, after explicitly telling Mr McSweeney in 2017 it must declare donations within a 30-day limit.
However, dozens of donations made to Labour Together between 2018 and July 2020 were not declared until after Mr McSweeney left the organisation that year.
Now the Conservatives say private legal advice given to Mr McSweeney contradicts Labour Together’s public claim the mistakes were due to ‘human error and administrative oversight’ and it had been as ‘open and transparent’ as possible.
Mr McSweeney initially did declare donations to the group when he took over as director of Labour Together in 2017.
However, early in 2018 he stopped reporting donations – apart from one disclosure of £12,500 from Trevor Chinn, a Jewish businessman and friend of Tony Blair.
It was only after Mr McSweeney left to work for Sir Keir as new Labour leader that his replacement, Hannah O’Rourke, found almost three years of donations worth £739,000 had not been declared and filed a series of ‘late’ declarations to the Commission.

Now, in a letter to the Electoral Commission, Tory chairman Kevin Hollinrake said the party has new information to justify the commission ‘initiating a formal inquiry and then to refer the incident to the police’ relating to ‘the breach of political finance laws’.
Mr Hollinrake said advice from lawyer Gerald Shamash written in 2021, which appeared to have been ‘passed from within the Labour Party to outside sources’, revealed discussion about how to handle the Commission – and admitted it would not be easy to explain Labour Together’s position.
Mr Hollinrake said Mr McSweeney was advised that Labour Together should blame the non-reporting of donations on an administration error.
But the Tory chairman believed the donations weren’t declared to protect the donors’ identities.
The row comes ahead of the publication next month of The Fraud, by journalist Paul Holden, which will include a detailed account of Mr McSweeney’s role in Labour Together.
The think-tank was a key plank of the drive by Mr McSweeney and his allies – including Lord Mandelson, who was sacked as US ambassador this month over links to paedophile Jeffrey Epstein – to topple Mr Corbyn from the party leadership.
Advance details from The Fraud have already prompted the resignation of Paul Ovenden, the prime minister’s director of political strategy, over sexual remarks made about Mr Corbyn’s former girlfriend Diane Abbott.
Asked for Mr McSweeney’s comment on the claims last night, No 10 referred The Mail on Sunday to Labour Together.

A spokesman for the organisation said: ‘Labour Together proactively raised concerns about its own reporting of donations to the Electoral Commission in 2020.
‘[Their] investigation, with which Labour Together fully cooperated, was completed in 2021. The outcome was made public.’
A spokesman for the Electoral Commission said it had ‘thoroughly investigated’ the late reporting of donations by Labour Together in 2021.
He added: ‘We were satisfied that the evidence proved beyond reasonable doubt that failures by the association occurred without reasonable excuse.
‘Offences were determined and they were sanctioned accordingly.’
