The founder of Moneysupermarket has sold off the last of his stake in the price comparison site, resulting in a £124m windfall and ending his 17-year dotcom rollercoaster ride with the firm. Simon Nixon, who launched the website in 1999, has been selling down his shares over the past few years and has today concluded his exit. He stepped down as non-executive deputy chairman at the end of 2015. He enjoyed a £98m payout in December when he last disposed of shares, after which he was locked up until the firm had reported its full year results on March 1. The disposal process has been bumpy at times, with a £100m stake sale last March cancelled less than a day after it was announced. This latest sale of his remaining 6.9pc stake in the company, carried out by his broker Credit Suisse, sent shares in the FTSE 250 firm down nearly 4pc. Mr Nixon founded the business after quitting an accountancy course at the University of Nottingham, which he later claimed was "boring".
