Mr Hill receives £ 10,000 per month for his travel to and from the US and other living expenses, in addition to his salary of £ 376,667 per year. He is the bank’s fifth-largest shareholder with a stake of around £ 110million.

A source close to the bank said Mr Hill was sometimes joined on his private jet trips to London by his wife and other InterArch employees, including Rodney Dean, the architectural firm’s creative director and the Mrs. Hill’s “right-hand man”. InterArch employees also stayed at the Mayfair apartment, the source said.

Ms Hill and her InterArch colleagues use desks at Metro Bank headquarters at One Southampton Row in Holborn when in town. If more than 50% of shareholders voted against Mr. Hill’s reappointment, he would be forced to resign because the vote is binding.

Mr. Hill was previously kicked out of the board of directors of a bank he founded – Commerce Bank in Philadelphia. He was ousted after regulators launched an investigation into his trade relationship. No action was taken against him, but he issued a “cease and desist” order restricting his real estate transactions.

A Metro Bank spokesperson said: ‘The president receives £ 10,000 per month to cover travel to and from the US and living expenses in the UK. How he travels and where he stays is at his discretion. Who travels with him and stays with him is not a concern of Metro Bank.
