The images posted on Facebook by DUP man Ian Stevenson

A DUP councillor celebrated his party's role as kingmakers at Westminster by posting a photo of a UVF flag flying from Downing Street.

Ian Stevenson, a former mayor of Ballymoney, wrote on Facebook: "Few changes made in Downing Street today."

It was accompanied by an image of the kerbstones at No 10 painted red, white and blue and the UVF and Northern Ireland flags erected outside.

Mr Stevenson, a member of Causeway Coast and Glens Borough Council, told the Belfast Telegraph that he had made a mistake in posting the photo.

"I thought it was an Apprentice Boys flag," he said. "I never noticed that it was a UVF one. I've no time for them and I don't endorse them."

The DUP councillor said he would be removing the image from his Facebook page.

A member of Ballymoney Free Presbyterian Church, Mr Stevenson hit the headlines when he cleared the drinks cabinet of alcohol in the mayor's parlour on taking office in 2011.
