Simon Trim has been named as the new chief executive of the Sporting Index Group, the world's largest sports spread betting business.
Trim's appointment follows the departure last month of former chief exec Warren Murphy, who led the betting firm for seven years.
Trim has been with Sporting Index for 18 years and was appointed managing director of Sporting Solutions, the B2B trading services division of the group, in late 2011.
"The Sporting Index Group has always been a quiet powerhouse within the gambling industry, offering a differentiated consumer betting product through Sporting Index and underpinning a lot of the recent in-play growth in the wider market through Sporting Solutions," new boss Trim said.
"It has never been in better shape to continue maximising its opportunities in the market and I'm delighted to have been chosen to take it forward."
The company, based in London, dominates the sports spread betting market with an estimated 80 per cent market share, though it also offers bets on global political and entertainment events.
Sporting Index was sold in March 2015 to an unnamed private investor. Private Equity owners HgCapital bought the firm in 2005 for £76m but decided to put it up for sale shortly after the 2014 World Cup.
