The multimillion-pound legal rows that have dogged Wembley stadium will still be rumbling on in 2009, 10 years after Lord Foster’s design was first unveiled, experts have predicted.

As the High Court case between main contractor Multiplex and steelwork specialist Cleveland Bridge enters its second week, other cases have yet to begin, including ones between Multiplex and Mott MacDonald and Multiplex and PC Harrington.

Multiplex alleges that Mott MacDonald owes it £253m for breaches of contract and acts of negligence.

It also alleges that PC Harrington’s work on the £45m concrete contract was defective and had to be carried out by others.

Peter Wickens, Mott MacDonald’s chairman, said: “The Mott Stadium Consortium (MSC) performed its contractual obligations to Multiplex professionally and diligently. MSC will vigorously defend any claim.”

Preliminary hearings into the PC Harrington case were held last November and into the Mott MacDonald case in January.
