The completion date of the new Wembley Stadium could be put back once more, says project contractor, Multiplex.

The Australian construction company building the £757m venue has said that it is now not expected to be finished until October.

Wembley was due to hold the 2006 FA Cup Final, but it was announced in March that the stadium would not host any events for the duration of 2006.

Multiplex said in a statement: "In order to achieve practical completion of Wembley Stadium certain works which are the responsibility of Wembley National Stadium Ltd (WNSL) rather than Multiplex must first be completed. WNSL has not begun some of these works." Details: www.multiplex.com.au
