JP Morgan chairman and chief executive Jamie Dimon will keep both jobs after shareholders backed him.

US investors meeting in Florida were voting on whether he would stay as chairman alongside his position in the other top seat as chief executive.

The company employs around 5,000 staff at its Chaseside headquarters in Bournemouth.

Shareholders voted 32.2% in favour of creating a new chairman, lower than last year when the vote was 40.1%.

Good corporate governance practice in the US and the UK suggests the two key jobs should be done by different people.

Last year JP Morgan Chase suffered a $6.2bn (£4bn) loss after trades made by the so-called London Whale turned out to be bad.

At the time Mr Dimon apologised and said the bank had “let a lot of people down.”

A group of shareholders have been demanding an independent chairman to help protect the bank from future trading fiascos.

Disgruntled shareholders expressed their displeasure at the bank's management however by re-electing three JPMorgan directors to the board with an unusually slim majority.

The three directors were on the board's risk management committee.
