Boris Johnson reportedly told a Whitehall investigation into the Downing Street flat refurbishment that he didn’t hand over crucial text messages sent to a party donor because he had a new phone number.
In December, the prime minister was accused of misleading Lord Geidt, the peer who oversaw the inquiry into the redecoration of the No 10 flat.
It emerged then that Mr Johnson had sent Whatsapp messages directly to Tory donor Lord Brownlow, something Lord Geidt had not been told about.
The prime minister has now reportedly tried to explain this omission by saying that he had changed his mobile phone number, according to the Financial Times.
The news comes as Mr Johnson faces pressure to act on rising energy prices.
Ministers have concluded that “something needs to be done” about the soaring cost of energy, according to Sky News.
Households are likely to face a big hike in energy bills on 1 April due to a predicted rise in the price cap.
This coincides with an increase in national insurance, and also comes as the cost of day-to-day living rises.
