SIR Keir Starmer said on visit to East Lancashire today that Boris Johnson could clear up questions over who initially paid for the refurbishment of his Downing Street flat in 30 seconds with a straight answer.

The Labour leader was in Rawtenstall on a local election campaign visit as pressure piled up on the Prime Minister over the £200,000 revamp and whether he said would rather see 'bodies pile high' than take the country into a third lockdown.

The Electoral Commission believes the Conservative Party may have broken the law over the flat renovations amid reports the costs were initially covered by donations and has launched an investigation.

Asked during his Rawtenstall visit if Mr Johnson should resign, Sir Keir said: "Boris Johnson needs to answer a very, very simple question which most people could answer.

"Who paid for the refurbishment of your flat.

"Now most people who have had their flat refurbished would be able to tell you who paid for it.

"He could end all of this questioning in about 30 seconds if he just told us.

"The big question here is why does he not want people to know the answer to that question.

"Yesterday he made a number of important statements on the record in Parliament. If it transpires that he has misled Parliament, then the Ministerial Code says then he should resign. But let's see.

"Most of these inquiries could be over in five minutes if he'd just organise for a camera and a microphone and said 'I'll tell you paid the initial invoice for the refurbishment of my own flat."

Mr Johnson said today he would co-operate with the Electoral Commission probe adding: "I don't think there is anything to see here or worry about."

He described the political storm over the flat renovations overseen by his fiancee Carrie Symonds as 'a whole farrago of nonsense' and the claims over the 'bodies pile high' comment as 'total rubbish'.
