WEMBLEY Stadium was hit with another dispute this week when electrical specialist SPL Installations walked-off the job following a payment row with labou r agency BMS.
SPL bosses plan to take BMS to adjudication over claims they are owed £300,000 in unpaid bills.
SPL boss Paul Gregory said: 'We have been on the job since day one with about 50 men but now we are at the end of our tether and pulled our team out on Tuesday.
'BMS has turned round and said they won't pay us but still want us to carry on working.
'We've now told them we are going to take them to adjudication under the terms of the Construction Act and we've got a very solid case.' BMS was unavailable to comment.
The organisers of a stadium building exhibition at the new Wembley have been forced to switch the event to November because of the delays that have engulfed the project.
The Stadia & Arena 2006 exhibition was scheduled to take place in the Great Hall at Wembley stadium on June 21 and 22.
But organiser Alad has put the exhibition back nearly five months to November 14 and 15.
Managing director Alan Levett said: 'The new dates are in a nonChampions League week, which is good because the vast majority of our audience are the guys who run the stadiums around Europe.'
