Officials at one of the city's biggest community centres are planning a right royal opening of their £3.2 million extension.

The Grange Interlink Comm-unity Centre, Great Horton, has asked the Duke of York to make a return visit next month to officially launch the development.

And a "mini mela", expected to attract about 1,000 people, will be held at an informal community opening on Sunday.

The centre includes a four court sports hall, changing rooms and a fitness centre, a multi-purpose hall for community use and other sports, separate day centres for men and women, information technology facilities and training.

There will also be a jobs search service, youth and homework clubs and a community health scheme.

Today, centre manager Imran Khan said they were in talks about the use of the top facilities by athletes training for the 2012 Olympic games.

He added London group Sk1 would perform in a road show in the centre's car park on Sunday and local people were also being invited on stage.

Mr Khan said they had decided to hold the free of charge community event because it would be impossible to invite everyone to the official opening.

"Prince Andrew visited us three years ago and we are hopeful he will be able to do the official opening in the middle of September. The development is already open and immensely popular. We are hoping we can tap into the Olympic games with world class facilities and are considering what we could contribute."

The existing centre, which was built in 1981, is still being used by the community but the extension is expected to attract thousands of people.

The dream of redeveloping the centre in Summerville Road, Great Horton, began seven years ago and funding has been provided from the Government's New Opportunities Fund, Sport England, the European Regional Development Fund, Neighbour-hood Renewal Fund, Waste Recycling Environment Ltd, Manningham and Girlington Regeneration Budget and Bradford Council. It was designed by Bradford architects Dean Woodward.

Members were jubilant when contractors moved onto the site last year because they said the area had been "forgotten" for years.
