Gail Sheridan, wife of the former Socialist MSP, is unlikely to face charges of stealing miniature bottles of spirits from her employer, British Airways, The Herald understands.

When Tommy and Gail Sheridan appear in court next week accused of perjury there will be no sign of the charge of theft brought by police in relation to her allegedly having a collection of souvenir miniatures in a display case at their home.

Crown Office sources admitted last night that the theft charges against Mrs Sheridan would not feature next Thursday, although it was claimed that theoretically these could be re-introduced later.

But The Herald understands that it is likely that the charges will be dropped against the former MSP's wife, who was suspended from her airline cabin crew job last month.

Last night, the Sheridan camp was convinced that the theft charges were dead in the water and were always intended as a crude way of applying pressure over the wider perjury allegations arising from Mr Sheridan's victory in the defamation action against the News of the World about his private life.

He won £200,000 but that prompted a police investigation into perjury which in turn led to his wife being charged, not just with perjury for supporting her husband but of the theft of miniature bottles of spirits.

Mr Sheridan claimed at the time of the theft charges that his wife was subject to a witchhunt for backing him in court.

The couple were refusing to comment yesterday on the basis of legal advice.

A Crown Office source said last night: "There is a long way to go yet in this case. Speculation as to any eventual charges is unfounded.

"In Scots Law the charges which appear in the petition at any first appearance are only initial charges and can be completely altered before the case is indicted, after the case has been further investigated and considered by the fiscal and Crown counsel."

Hugh Kerr, the former Labour MEP who became an aide to Mr Sheridan and followed him from the Scottish Socialist Party across into the breakaway party Solidarity, said last night that the news fitted with what they had been hearing about the process.

"Solidarity are delighted to hear that Gail Sheridan is not being charged with theft. This trumped-up charge was clearly an attempt to discredit Gail as a witness and pressurise her and Tommy over the perjury case," he said.
