Barclays deputy chairman Mike Rake has said he will leave the bank's board in 2015 and is set to join the board of Worldpay by September 2015.

The possible departure of Rake, who is one of the most influential businessmen in the UK, comes a week after Barclays fired its chief executive Antony Jenkins on 8 July.

The bank does not have an official comment but a spokesperson could confirm to IBTimes UK that Mike Rake has not officially resigned yet.

Rake has not signed a contract with payment services company Worldpay and the company could not provide any information, but he is expected to join the board by 1 September.

Rake, who is thought to be a key player in Barclay's quest for a new chief executive, has been on the bank's board since 2008.

As the current chairman of the Confederation of British Industry and former BT Group chairman, Rake is a respected figure in the City.

Barclays' share price has climbed by more than 13.5% in 2015 and has jumped by 7.6% to 276.96 since Jenkins was fired.
