Home Secretary Amber Rudd revealed as director of two Bahamas' companies

British Home Secretary Amber Rudd is facing calls to resign after a Guardian investigation found leaked information regarding undeclared business practices in the Bahamas.

The investigation claimed that Rudd held a director's position at two companies in the Carribean tax haven. She had previously defended former prime minister David Cameron over his role in his father's investment company in the country without mentioning her own possible interest.

Files leaked to German newspaper Süddeutsche Zeitung supply a list of 175,000 registered companies in the Bahamas, with Rudd being named as director of Advanced Asset Allocation Fund and Advanced Asset Allocation Management.

The Home Secretary's career before politics has been shrouded in doubt and questionable companies, such as her involvement with Monticello.

She resigned as a director of the company just five months after a dubious interview by co-director Mark O'Hanlon led to a rapid share price increase before trading was suspended on it.

A spokesman for Rudd denied involvement in any wrongdoing.

"It is a matter of public record that Amber had a career in business before entering politic," the spokesman told the Guardian.

"Monticello was thoroughly investigated 16 years ago and those who acted wrongly were identified and prosecuted."
