Lord Alan Sugar has signed up for more of the BBC series The Apprentice.

Writing on Twitter he said: "I have agreed to do 2 more series of The Apprentice, making it 10 years."

The 65-year-old businessman started fronting the show in 2005.

Karren Brady and Nick Hewer also appear on the show with the winner of the process becoming a partner of Lord Sugar's and getting an investment from him of £250,000.

Last year's series was won by former wrestler Ricky Martin.

He pitched a plan for a niche recruitment company specialising in the science industry.

One of the runner-ups, Nick Holzherr, has also since secured funding to launch his idea, a food website that creates online shopping lists based on recipes.

The show won a Bafta award for best feature in 2006 but has come in for criticism from some former contestants.

Lucinda Ledgerwood and James Max have both said that the show is designed to entertain viewers rather than to test business skills.

Lord Sugar also revealed in his autobiography that boardroom exchanges were heavily edited to create tension.
