Rishi Sunak's wife has shares in her family's tech firm that are worth £430million, making her one of Britain's wealthiest women.
Akshata Murthy and her relatives hold a multimillion pound portfolio of shareholdings which the Chancellor, who met his future wife while studying at Stanford University, California, has not declared in the register of ministers' interests.
The assets make Akshata richer than the Queen, who is estimated to be worth £350million, according to the Sunday Times Rich List.
The latest revelation comes after Mr Sunak faced demands to reveal details of his financial interests last month, after it emerged he set up a 'blind trust' when he was made Chief Secretary to the Treasury in July last year.
But critics said there was still risk of conflict as Mr Sunak - reputed to be the richest MP - is aware what he put into the trust.Insurance Loans Mortgage Attorney Credit Lawyer
