Boris Johnson did not break the ministerial code over the funding of the Downing Street flat refurbishment, a report says. But Lord Geidt, the prime minister's adviser on standards, found he had "unwisely" allowed work to go ahead without "more rigorous regard" for how it would be paid for *.

He confirmed that a Tory donor had settled an invoice for some costs. But Mr Johnson had been unaware of this, Lord Geidt added. No conflict of interest had arisen over the refurbishment, which began in spring when the prime minister was in hospital with Covid, he said.

The government said official advice had been followed "throughout".
