IOC president Jacques Rogge has given London 2012 Olympics some breathing space despite the latest delay over finalising the venue for badminton and rhythmic gymnastics.

London organisers want the sports to agree to move venue to Wembley but the international federations have delayed a decision until March citing concerns about the length of travel time from the Olympic Park in the east of the capital.

In October, London 2012 Olympics were warned by the IOC it was 'urgent' they resolved the issue by November and now London chiefs will have to report to the next IOC session in Vancouver on February 11 they have still not finalised the venues.

But Rogge claims he is not worried about the latest hold-up.

He said: "It's not really a concern in that we know a solution is being prepared and discussed with both federations.

"They are in the final straight and the result will be very satisfactory for the two federations.''

The sports were originally planned to be sited in a temporary venue in Greenwich, near the O2 arena.

Rogge also expressed his confidence the weather and concerns over the budget in the wake of the credit crunch would not spoil next month's Winter Olympics in Vancouver.

The Canadian city has been experiencing some unseasonally warm weather, but Rogge said the latest weather report showed the mountains areas where the skiing events will be staged had more than enough snow, and there was a contingency plan in place.

"There is a permanent contingency planning for the entire duration of the Games,'' said Rogge.

"The latest is that Whistler mountain is absolutely fine and Cypress mountains is absolutely fine on the track.''

"In terms of the budget, we had some savings to do in the budget of VANOC [Vancouver organising committee] but these were chosen very carefully as to not impact the Games and experience for the athletes. The athletes won't feel anything of the financial crisis.

"Vancouver can say that everything is ready now. I am very optimistic for the staging of these Games."
