Boris Johnson has been accused of making a "mockery" of MPs standards following reports he is set to be cleared of breaking rules over the donation for his Downing Street flat refurbishment.
The Prime Minister faced allegations that he misled his ethics adviser, Lord Christopher Geidt, over what he knew about a controversial refurbishment of his No 11 flat.
But senior officials have told the Financial Times, the PM is set to be cleared of breaking the ministerial code.
One senior official told the newspaper: “Geidt makes clear the situation is a total mess. But at the same time the fundamental conclusion is that the PM did not deceive and did not break the ministerial code.”
Earlier this month, the Conservative Party was fined £17,800 by the elections watchdog, after it said the party had failed to correctly declare donations worth £52,800 from a firm owned by Tory peer Lord Brownlow.
The report found the Prime Minister had WhatsApped Lord Brownlow in November 2020 to ask for more funds towards the luxury makeover of the flat he shares with his family.
The finding conflicted with Mr Johnson's claim to Lord Geidt that he wasn't aware of the source of funding for the flat until February 2021.
Recently, Lord Geidt, the independent adviser on ministers’ interests, is said to have exchanged a series of letters with the PM in recent weeks, the newspaper reported.
According to reports, the letters could be published as soon as next week.
In May, Lord Geidt ruled that the PM had "unwisely" allowed the works to go ahead without thinking about who would foot the bill but he had not broken the ministerial code.
Angela Rayner, Deputy Leader of the Labour Party, has called on Lord Geidt to publish "all his correspondence" with the PM over the flat donation "as a first step towards providing full transparency".
"After the Electoral Commission ruled that the Conservative Party broke the law on declaring donations, the Prime Minister has made a mockery of the standards the public has a right to expect.
"While the British public is facing a cost of living crisis, Boris Johnson is busy writing to his own adviser about why he did not give him all of the information he needed for his investigation.
“Lord Geidt should publish all his correspondence with the Prime Minister as a first step towards providing full transparency into how Boris Johnson is explaining away his WhatsApp messages with Tory donors.
“It is embarrassing that when the country needs real leadership, Boris Johnson is busy trying to clear up his own personal mess.”
Prime Ministers get an annual grant of £30,000 towards the upkeep of their home in No 10.
The PM and his wife Carrie exceeded this cap and reportedly spent as much as £150,000 on the makeover.
Some of the bill was picked up by the Cabinet Office on the condition it would be reimbursed by the Tories.
Downing Street has been contacted for comment.
Number 10 officials previously insisted that the Prime Minister had acted in accordance with the rules at all times.
