British parliamentarians have come under further fire over offshore assets after a Tory party official admitted having assets in Bermuda.

In an article published online yesterday,The Sunreported that 12 senior Tory officials had put their assets in offshore blind trusts to avoid “clashes with their jobs”, including Robert Halfon, the Tory party deputy leader.

Mr Halfon admitted holding shares in Jardine Matheson, a firm based in Bermuda with headquarters in Hong Kong.

The article explains that blind trusts are used to prevent ministers from using their positions from influencing their own investments, but also keeps their financial affairs private.

It quotes Johnathan Isaby, chief executive of the Taxpayers Alliance, as saying: “Taxpayers deserve full and proper transparency so that they can make their own minds up on whether their politicians are acting in the nation’s interest rather than their own.”

The statement comes in the wake of a public furore over the Panama Papers — a leak of 11.5 million business documents which allegedly reveal tax avoidance and evasion by many international figures.

Labour MP Wes Streeting has called on ministers to “come clean” in the wake of the leak, stating that Prime Minister David Cameron’s “shifty” response to questions about his own tax arrangements have left the public unsure if politicians are willing to seriously tackle the issue of tax havens.
