"The party constitution states if somebody brings the party into disrepute, they can be disciplined. I would stress Harry Gregg is a gentleman and what was said about him was totally
Harry Gregg spent 10 years with Manchester United and gained 25 caps for Northern Ireland.

In February that year, he was involved in the Munich air disaster when a plane carrying Manchester United footballers back from a European tie in Belgrade crashed in a blizzard after refuelling at Munich airport.
Mr Gregg pulled to safety from the wreckage one of his fellow passengers, the pregnant wife of a Yugoslav diplomat.
