Personal finance journalist Martin Lewis has secured his own multimillion-pound fortune by agreeing the sale of his website for up to £87 million.

MoneySavingExpert.com was set up by Mr Lewis in 2003 and will be bought by the price comparison website MoneySupermarket.com.

Mr Lewis, who is well known as a television pundit on money matters, will receive £60 million upfront in a mixture of cash and shares and a further £27 million conditional on meeting targets over the next three years.

He plans to donate £10 million to charity from the deal, including £1 million to Citizens Advice, while he will retain full control over the website.

According to Google Analytics, the MoneySavingExpert website attracted 39 million unique visitors and around 277 million page impressions in the year to October 31.

It generated revenues of £15.7 million over the same period.
