A COMPANY owned by Prime Minister Rishi Sunak’s wife must fulfil “all its liabilities to the British taxpayer” while being wound up, Labour frontbencher Pat McFadden has said.

Mr McFadden, the party’s national campaign co-ordinator, has written to Deputy Prime Minister Oliver Dowden following last week’s annoucement that Akshata Murty’s investment company Catamaran Ventures UK is be liquidated.

The company made headlines last May when it emerged that it held shares in Study Hall, an education start-up which had received almost £350,000 of government grant money.

Mr McFadden urged Mr Dowden to ensure that the couple’s interests continue to be properly declared in the register of ministerial interests during the closure.

He also asked what impact Catamaran’s winding-up would have on Study Hall and “any other companies in which Catamaran retains a stake,” as well as whether the firm would be “fulfilling all its liabilities to the British taxpayer” by arranging to pay any outstanding taxes.

Mr Sunak’s family finances previously faced scrutiny while he was chancellor when his wife’s “non-dom” tax status was revealed.

Following the controversy, Ms Murty declared that she would pay British taxes on all her worldwide income.

Mr Sunak also faced a standards probe over concerns that he did not declare Ms Murty’s financial interest in Koru Kids, a childcare agency that benefited from a Budget policy providing incentive payments to childminders entering the profession.

In his letter, Mr McFadden also referenced the Prime Minister’s most recent appearance before the Commons liaison committee, during which he was grilled by a series of senior MPs.

Mr Sunak told the committee’s Tory chairman Sir Bernard Jenkin in December that he would write to the panel of MPs if he had failed to mention any interests which he later decided were relevant to their questions.

Regarding the latest liaison committee session, Mr McFadden asked: “Will this include any interests beyond Catamaran Ventures and cover responsibilities relating to the Prime Minister’s position both as a minister and as an MP?

“It is vital that these questions are answered in the interests of, to quote the Prime Minister himself, ‘integrity, professionalism and accountability’,” he added.

Mr McFadden rejected a suggestion that his party was trying to make “political capital” out of the issue.

Downing Street and the Conservative Party were contacted for comment.
