Rishi Sunak has promised to release his full tax return, lifting the lid on his vast wealth.
The PM is the wealthiest leader the country has ever had. He and his wife Akshata Murty have a £730million fortune, more than twice that of the King.
Asked if he is willing to publish his full tax return, Mr Sunak, who is attending a G20 summit in Bali, said: “Yes, of course.”
He added: “That is the established precedent and I'd be very happy to follow the precedent.
“In terms of timing, I will have to speak to the Cabinet Office and figure out the right way that happens. But yeah, I have no problem doing that.”
Questioned on whether he will release the document within his first year as PM, he said: “Yes, of course.”
Pushed on whether it will come before Christmas, he replied: “I have to talk to the Cabinet Office to check on the precedent for how those things happen, but I have absolutely no trouble doing it.”
Mr Sunak’s pledge to reveal his tax affairs comes after he yesterday refused to say if he has private healthcare.
The PM claimed it was “not appropriate” to be asked whether he relies on the health system in the same way as ordinary families.
David Cameron in 2016 released a summary of his tax returns from 2009 to 2015 in an attempt to defuse a row over his personal finances.
A few months later, Theresa May published a tax summary during the Conservative leadership contest, but she refused to do so during her time in No10.
Boris Johnson released his tax details when he was Mayor of London, but not when he was PM.
Mr Sunak faced a backlash earlier this year while chancellor after it emerged his wife was a non-dom, meaning she did not have to pay UK taxes on her overseas income. It is estimated this would have saved her £2.1m a year in UK tax.
After details of her non-dom status appeared in the press, Mr Sunak initially said his wife had not "done anything wrong" and it was unfair to attack her as a "private citizen".
But following days of negative headlines, Ms Murty announced she would pay UK on her overseas income.
A non-dom is someone who lives in the UK but declares their permanent home to be in another country.
