Newspaper headlines: 'Boris painted into corner' and how to get 'fancy wallpaper'

Many of the front pages focus on the decision by the Electoral Commission to investigate the funding of work on Boris Johnson's Downing Street flat - and the angry exchanges about the issue at Wednesday's Prime Minister's Questions.

According to the Guardian, Mr Johnson was "goaded into a fury" by the Labour leader, Sir Keir Starmer, in what the Metro calls "their fiercest Commons clash yet".

"Boris gets a pasting", claims the Daily Star, which says the prime minister was left "raging" by the bust-up "in which he was dubbed Major Sleaze". The Financial Times says Mr Johnson was asked bluntly "are you a liar?" by the SNP and responded by accusing opposition parties of "obsessing over issues of little interest in the lives of most voters".

The Daily Mail says the "bombshell" move by the Electoral Commission could see Mr Johnson become the first serving prime minister to be interviewed under caution in relation to an alleged breach of the law.

The Times claims there is concern within Downing Street that the possible involvement of a Tory donor in financing the flat renovation "has left a damaging paper trail" at Conservative Party headquarters.

"There was a very limited number of people who knew about the funding arrangements," a government source tells the paper. "It's not clear how this will end".

The Daily Mirror dismisses what it calls a "supposedly independent probe" headed by the Queen's former chief aide Sir Christopher Geidt - by highlighting the reaction of the shadow minister for the Cabinet Office, Rachel Reeves.

She is quoted saying: "In our country, the police don't require the permission of a thief to investigate a burglary." Boris Johnson has insisted no rules were broken.

An acknowledgment by England's deputy chief medical officer that it's "incredibly safe" for two fully vaccinated people to meet is the main news for the Daily Telegraph.

It says Professor Jonathan Van-Tam told Wednesday's Downing Street briefing he was "highly confident scientifically" that any such meeting presented little risk - but went on to urge people not to get together until more jabs are administered.

The Times notes remarks by the head of immunisation at Public Health England, Mary Ramsay. Speaking to MPs, she suggested vaccinated people might be given different social-distancing advice in the summer before insisting that, for now, the government was not in favour of creating what she called "privileged individuals".

The front page of the Sun marks the court appearance by the Wales manager, Ryan Giggs, who pleaded not guilty to two assault charges and another of coercive control.

It says the former Manchester United star "stood grim-faced in the dock" as prosecutors accused him of "deliberately headbutting" his former girlfriend at his home in November last year.

Mr Giggs was released on bail ahead of a hearing at Manchester Crown Court next month.
