DUP sports minister has refused an invitation to visit Celtic Football Club in Glasgow, accusing the club of not doing enough to stop sectarian singing.
Gregory Campbell said Glasgow Rangers had taken steps to stop their fans singing sectarian songs but Celtic had not done enough.
Mr Campbell said "The recent songs about the IRA would suggest an awful lot more work needs to be done. It would call into question my attendance at the ground."
Mr Campbell, acting in his role as an MP only and not as sports minister, had earlier written to Celtic to complain about being abused by fans during a ferry crossing to Scotland to attend a Rangers game.
The letter was addressed to the former Northern Ireland Secretary, and chairman of Celtic, John Reid.
Mr Campbell has declined an invitation to Parkhead saying it would send out the wrong message, but denied he was setting preconditions.
