Coutts bankers accused of inappropriate conduct escaped punishment, The Telegraph understands.

On Thursday the Wall Street Journal reported that the bank had investigated sexual harassment by star banker Harry Keogh.

Mr Keogh, 57, who still works at the bank, was accused of inappropriate behaviour including sexually harassing a graduate trainee at a company dinner and touching her groin in front of colleagues at a meeting, the newspaper reported.

But an investigation by the bank found that while standards in his whole team had dropped below par, he was the only one to be disciplined.

Sources suggested to this newspaper that the "sexually charged" culture extended beyond Mr Keogh.

Speaking to The Telegraph a former Coutts employee, who wanted to remain anonymous, said she and her colleagues would regularly go on nights out with the men at private members clubs.
