One of London’s largest and most successful hedge funds is considering moving to Switzerland because of uncertainty about the UK’s tax regime, writes the Sunday Telegraph.

Brevan Howard, which manages $22bn of hedge fund assets and employs 250 people, said this is due to the government’s tough line on non-doms.

The fund manager, run by prominent Conservative Party donor Alan Howard , has sounded out officials in several cantons in Switzerland with a view to opening an office which could also serve as its new headquarters.

Five out of the fund's eight founding partners are believed to be registered as non-doms in Britain, all of whom have been upset by the Government's attack on the tax status.
