ParalympicsGB officials have revealed that they are unimpressed that several nights of athletics action have run behind schedule.
Last night's final event, David Weir's win in the T54 5000m, was half-an-hour behind its scheduled start, by which time spectators were having to leave the stadium.
"We have fed our concerns to Locog as we want things to run to time," ParalympicsGB chief Craig Hunter told The Telegraph.
"It would have been better for David Weir to compete in front of 80,000 fans, not 75,000."
GB have racked up 19 gold medals in the first five days of action.
