The trial of four former British Airways executives over price fixing allegations has been adjourned until next week at the earliest.

The defendants are accused of conspiring with Virgin Atlantic to fix fuel surcharge prices between July 1 and April 20 2006.

The jurors at Southwark Crown Court were told this morning that an unspecified difficultly had arisen meaning Thursday April 22 would be the earliest the trial could begin.

The quartet which includes former commercial director Martin George, former sales and marketing director Andrew Crawley, former head of communications Iain Burns and former sales director UK and Ireland Alan Burnett, deny the charges.
