Angela Knight, the head of the British Bankers' Association, is to join a new trade association for the UK energy sector when she steps down from the BBA at the end of July after five "hairy" years.
Ms Knight said in April she planned to leave the BBA, and Energy UK said yesterday she would join as chief executive in the summer.
Energy UK was formed in April and represents 70 companies, from small generators and energy services companies to large utilities.
The former politician was often outspoken in her five years as BBA chief executive, defending banks over executive pay, taxpayer bailouts and the mis-selling of products.
The association has not yet named a successor.
