Greg Coffey, the "rock star" of the global hedge fund industry who owns a large chunk of the Hebridean island of Jura, is planning to take early retirement at the age of 41.

The man who has amassed a fortune of £430 million announced in a letter to investors that he is retiring from Moore Capital Management, run by billionaire Louis Bacon, after 20 years in the industry.

Mr Coffey, whose 14,000-acre Ardfin Estate land is home for most of the island's 200 residents, wrote: "After nearly 20 years in the financial markets, I've decided to leave the industry.

"The demands of my growing family mean that I am unable to commit to the market with the same intensity going forward."

Mr Coffey bought the Ardfin Estate, which includes seven uninhabited islands and the main settlement of Craighouse, in 2008, when it was on the market for around £3.5m.

In July, he drew up ambitious plans to create a world-class 18-hole championship golf course as part of a major investment on the estate.

The financier, who insisted on wearing leather jackets and casual clothes instead of suits, said last year he was determined to have his family spend as much time as possible in his home country, Australia, and that he and wife Ania Brzezinski, a former financial analyst, were already wrestling with the fact that his work required him to be in London.
