ROCK CONCERTS

Following the FA decision, rock concerts by Bon Jovi and the Rolling Stones at Wembley may have to be cancelled or re-located while the rugby league Challenge Cup final in August may also have to find an alternative venue.

"We do not want to set deadlines on when the stadium will open and be faced with the constant speculation surrounding this as we approach individual fixtures," the FA said.

"Therefore, we believe it is important that we are transparent with our plans."

Earlier this month a 50-tonne steel roof girder slipped out of place at Wembley, forcing the evacuation of the 3,000 site workers. Further delays have been caused by drain and sewer problems and a dispute involving steel sub-contractors.

Multiplex said on Friday that WNSL, a subsidiary of the FA, bore some responsibility for the delay because it had opted to install finishing touches like retail units and turnstiles only after construction work was complete.

"As the client has chosen not to integrate their works and operational activities, these works will complete after our forecast date for substantial completion of the stadium," a company spokesman said.

"The question of events therefore rests with WNSL and the Football Association."

This year's FA Cup final on May 13 will take place at Cardiff's Millenium Stadium.
