The investment chief of Electra Partners has said there will be no change in the firm's strategy, despite the chairman of the listed private equity trust that is its main client resigning after a battle with US activist Edward Bramson.

Sherbone Investors - run by Bramson - on November 5 won a shareholder vote giving it two board seats at Electra Private Equity. Shortly after the vote, the listed trust's chairman Roger Yates resigned.
