The family of murdered banker Alistair Wilson voiced their ‘outrage’ last night after it emerged a senior officer who misled them is in line for a major promotion.

Detective Chief Superintendent Paul Livingstone, who was found guilty of misconduct, has been selected for a prestigious training course – and is being groomed to fill a vacant slot as Assistant Chief Constable.

His selection was delayed after the row over the Wilson case but Chief Constable Jo Farrell has now given Mr Livingstone her backing to take part in the elite course – leading the victim’s family to claim they have been ‘betrayed’.

Detectives investigating the 20-year-old unsolved murder of Mr Wilson, who was shot dead on his doorstep in Nairn, had been set to arrest a potential suspect, which it was hoped could lead to a breakthrough.

The arrest, planned for May 15, 2023, was halted at the last moment, with Mr Wilson’s family only finding out after they contacted a liaison officer for an update.
