Several Sunday front pages preview what may appear in Wednesday's Budget. The Sunday Telegraph reports that the chancellor is considering a carbon charge on imported fuel. The paper calls it a “green tax” and says the move could push up prices at the pumps.

The Sunday Times reports that billions of pounds of new funding will go to defence. Two government investment funds will also receive money, which will be invested in UK defence firms.

Housing and pensions

The Sunday Mirror welcomes news that £1bn will be committed to council and affordable housing. The paper says this is equivalent to building 10,000 homes. It adds that the government also plans to help more councils borrow to build homes by extending preferential rates. The paper's editorial says Britain will be a happier place when everyone has a secure roof over their heads.

The Sunday Express calls on the government to say whether it intends to bring forward the planned rise in the state pension age to 68. The paper says there are concerns the rise could take effect in 2037, rather than the mid-2040s as originally planned.

Artificial intelligence and tax

In an interview with the Observer, Microsoft co-founder Bill Gates describes the advent of artificial intelligence as an “evolutionary event”. He says people will no longer be the most intelligent things on the planet. He adds that governments will need to find new sources of income to meet the needs of people who lose their jobs. Gates also says billionaires should pay more tax. He claims he would have paid more than double the amount he has paid so far in his life.

Duchess of Sussex and Thomas Markle

The Sun on Sunday reports that a friend of the Duchess of Sussex says she is “concerned” that the Met Police did not act on a letter accusing her estranged father, Thomas Markle, of child sexual abuse. “They had the opportunity to pass it on to other relevant law enforcement authorities but chose not to,” the friend said.

In an interview with the Mail on Sunday, Markle denies all the allegations made against him. Markle, who had a leg amputated last year, told the paper: “I am not well enough to go to the Philippines but I will speak to anyone who wants to talk to me. I have nothing to hide.”

Emergency stockpiling

The Sunday Telegraph reports that wind-up radios are selling out after the government's emergency stockpiling announcement. It says sales increased fivefold at some retailers. An industry source said some shops were surprised by the advice that people should keep three days' worth of food and water. The announcement came just a day after a worldwide effort to fix vulnerabilities in the software that underpins the internet. One business owner told the paper: “I thought my phone was glitching or had been hacked when I saw the number of orders coming in.”
