North Lanarkshire Council has launched an investigation into 'serious allegations of corruption'.
Leader of the council, Jim Logue, ordered the investigation after he received an anonymous letter about corruption in the council's procurement processes.
He said the council has made the police aware of the situation and promised to hand over evidence discovered by the council's internal audit team.
Mr Logue said: 'These allegations, which are detailed, concern some of the council's procurement processes. If true, they are extremely serious.
He added: 'It is essential that the people of North Lanarkshire are able to have full confidence in the way the council conducts its business and I am determined that we are transparent at all times.
'Although these are currently unsubstantiated, anonymous allegations I believe that it is right to carry out a full investigation and share any evidence which comes to light with the police.'
Mr Logue declined to comment any further on the nature of the allegations while the investigation is underway.
