Chart star Calvin Harris has been ranked one of the wealthiest young stars in the music world with a fortune estimated at £30 million.

The Dumfries-born star is second only to pop queen Adele - who has seen her fortune swell by around 50 per cent in a year when she released no new material - who tops the Sunday Times Rich List's countdown of the biggest financial successes in the music world aged 30 and under.

Superstar DJ Harris, 30, has had a string of major hits with nine top singles from his latest album 18 Months and has worked with acts such as Cheryl Cole, Rihanna and LMFAO. Last year he was named songwriter of the year at the Ivor Novello Awards.

The former shelf-stacker - whose real name is Adam Richard Wiles and who is dating singer Rita Ora - is said to be able to command £100,000 for a night's work as a DJ in Las Vegas.

Cheryl Cole, who has recently signed up for a return to The X Factor panel, drops to third place from last year's number two although she has banked a further £2 million, according to the compiler of the list, Philip Beresford.

The five members of One Direction take joint fourth place with an estimated £14 million each, although they have a combined fortune of £70 million. Niall Horan, Zayn Malik, Harry Styles, Louis Tomlinson and Liam Payne are thought to have seen their finances swell by £9 million in the past 12 months, which has seen them tour and release a movie and a third album.
