The chancellor has written to the prime minister asking him to refer him to the Independent Adviser on Ministers’ Interests to determine whether all his interests were “properly declared”.
In a tweet, Rishi Sunak said he had “always followed the rules” and that he hoped the review would “provide further clarity”.
In the letter Mr Sunak said he was asking Boris Johnson to refer him “given the recent speculation around my declarations”.
The chancellor has been under pressure in recent days following revelations that he held a US green card while chancellor – requiring him to be loyal to the US – alongside questions about his wife’s tax affairs.
His wife has said she will now pay UK tax on her worldwide income.
“My overriding concern is that the public retain confidence in the answers they are given and I believe the best way of achieving this is to ensure those answers are entirely independent, without bias or favour,” the letter states.

“To that end I would recommend that Lord Geidt makes all his conclusions public. I am confident that such a review of my declarations will find all relevant information was appropriately declared.
“I have throughout my ministerial career followed the advice of officials regarding matters of propriety and disclosure and will continue to do so so,” he added.
