Newspaper headlines: 'PM urged to come clean' and 'June olé days'

"So can Boris wallpaper over the cracks?" asks the Metro, as some of Wednesday's papers continue to try to establish how the Prime Minister paid for the renovation of his Downing Street flat.

In a nod to the 1990s, the Daily Mirror describes this row as "Cash for Curtains". It says Boris Johnson is "mired in scandal" with Labour accusing him of lying.

The Guardian reports there is "growing disquiet" within the Conservative Party about the issue, with senior Tories wanting the Prime Minister to "come clean" about the funding of the refurbishment.

Britons will be able to enjoy "June Olé Days" in Spain, according to the Sun. The paper says travel will involve a digital health pass, following talks between the two governments.

The Spanish tourism minister, Fernando Valdes Verelst, has said he hopes his country will also be included on the travel "green list" by June, meaning passengers will not need to quarantine when they return to the UK. But the Daily Telegraph says this is not guaranteed, with Spain looking at a "green corridor" instead, allowing just vaccinated Britons to travel.

Closer to home - and analysis by the Times has found that more than 38 million people in England live in areas that are recording virtually no new cases of Covid. It means 70% of people are in parts of the country where a maximum of two infections were reported in the latest weekly data.

The government's scientific advisers say the figures show that the timetable for lifting the lockdown remains on track. But Professor Alastair Grant, from the University of East Anglia says some "deprived inner-city areas" in places such as Bradford and Leicester are still struggling - because of low take-up of the vaccine.

The i paper reports that the Post Office has warned the government it could require a bailout of hundreds of millions of pounds - if it loses a new legal case. It reports how 10 sub-postmasters want to be considered employed workers rather than independent contractors.

If they're successful, the Post Office could face claims from 8,000 others for pay and compensation going back more than 20 years. One accountant has told the paper the total bill could be more than £400m, but that could increase if sick pay and pensions are factored in.

"China braced for population fall" is the headline accompanying the Financial Times lead. People familiar with the latest Chinese census have told the paper the total population is likely to be less than £1.4bn.

It would be the first fall for six decades and comes despite a relaxation of strict family planning policies. Analysts say the population decrease could hit the Chinese economy hard - affecting everything from consumption to care for the elderly.

"Time for a Blair cut," is the Daily Mail's advice to Tony Blair after he appeared in an ITV News interview with a lockdown mullet. The paper says his appearance left viewers "utterly transfixed".

The Daily Telegraph considers whether it was the programme's "mane item", while the Daily Mirror thinks he may have drawn inspiration from the late nightclub owner Peter Stringfellow.

The interview itself was about Scotland's political future, leading the Times to question whether Mr Blair had granted devolution to his own locks.
