Matt Foster could well be a few pounds lighter than usual when he meets Prime Minister Tony Blair at No 10 Downing Street tonight.

Foster will be among 80 'young' leaders socialising with Blair at the iconic Prime Minister's residence as recognition for his outstanding work in the Keighley community.

Not usually of a nervous disposition, Foster admits he has his own way of dealing with anxiety.

"I wouldn't class myself as the nervous type and I'm not one to class any one person as better than any other, but these are important people, so it is a bit a nerve-wracking," admitted Foster.

"Before matches I usually spend a lot of time on the toilet, so I hope I'm not like that. It's a big part of my pre-match routine - getting myself to weigh less so I'm a little bit quicker on the field!"

The Cougars' full-time development officer, Foster has run coaching clinics in 46 Keighley primary schools. Sports minister Richard Caborn was impressed on a recent visit to examine the club's community programmes and, as a result, Foster received an invitation to meet the Blairs at No 10.

"They are rewarding young community leaders - I don't know how I slipped into the young bit - for bringing communities together," explained Foster.

"I laughed it off a little bit when I first got the invitation but as it has got closer I have got a little bit more nervous. Ten Downing Street is not a real place; it is like a figment of your imagination. Knocking on the door will be quite surreal."

Yesterday the Cougars eased into the fourth round of the Challenge Cup with a 62-14 win over Russian side Strela Kazan. After missing out on a potential money-spinning tie last year when they went out to amateur minnows Bradford Dudley Hill, Foster is hoping tonight's draw will be kind to the club.

"Leeds away would be nice. It would be tough but that is what you play rugby for, to play against teams like that."
