The man dubbed Britain's answer to Bill Gates will address an audience of more than 250 people at the annual review of a Bradford-based charity tomorrow.

Businessman Reuben Singh, said to be the world's youngest self-made millionaire, tops the guest list for this year's QED annual review.

The entrepreneur, who is chief executive officer of alldayPA.com, recently topped a league table of British businessman - beating off the challenge of Richard Branson and Anita Roddick.

He is the latest in a succession of high-profile names to feature at the annual event organised by QED, the charity which campaigns for social cohesion alongside religious and cultural diversity.

Other speakers at the event include Lord Filkin, Parliamentary Under Secretary for Race Equality, Community Policy and European and International Policy, and journalist Sir Mark Tully, an expert on the Indian sub-continent.

The event will also see the launch of QED's innovative new Welcome to Britain project which aims to support the social and economic integration of immigrants from South Asia.

Mohammed Ali, founder and chief executive of QED UK, said he was looking forward to the occasion.

"We are delighted to attract these guests to the event - it is the tradition of QED to attract the very highest quality speakers," he said.

"There will be around 250 people in attendance from right across the community and from all parts of the country. This is a very multicultural and multiracial kind of event.

"This is an opportunity for people from various community groups to rub shoulders with some of the leading names from the world of business.

"It will be a chance to hear of our own work in Yorkshire and farther afield and also to find out why it is needed from political, business and media experts."

Last year trade and industry secretary Patricia Hewitt was among the speakers at the review. This year's event at the Hanover International Hotel is by invitation only and starts at 5pm.
