MP Michelle Thomson has offered to help police with their inquiries into property deals conducted five years ago, her solicitor has said.

Ms Thomson's membership of the SNP was suspended when she withdrew herself from the party whip at Westminster after details of the investigation emerged.

She has denied any wrongdoing and a statement issued through her solicitor Aamer Anwar said she had taken the action in order to "clear her name and return as quickly as possible to the front line of politics".

SNP leader and First Minister Nicola Sturgeon yesterday said the party had no knowledge of Ms Thomson's business dealings when she was selected as a general election candidate.

The statement from Mr Anwar said: "Over the last few days individuals have demanded full transparency from the SNP and the First Minister as to what they knew of the detailed nature of Michelle Thomson's business dealings several years before she became an MP - the simple answer is none at all.

"Michelle Thomson maintains that she has always acted within the law.

"In the interests of her constituents and her party, she thought it best if she voluntarily withdrew from the party whip.

"There was no requirement for her to do so, even though she knew it would automatically lead to her suspension from the party. She did so in order to clear her name and return as quickly as possible to the front line of politics.

"To that purpose, we have contacted Police Scotland at Mrs Thomson's request advising them of her wish to assist with their investigation if or when they wish to speak to her.

"In the meantime, we would strongly advise those who should know better to tread extremely carefully and not prejudice a live investigation."

Mr Anwar said Ms Thomson, who was elected in May, was grateful for messages of support she had received but had been advised not to make any further comment until the investigation concludes.

"She maintains her commitment to the ideals of the SNP and will continue to work on behalf of her constituents," the statement added.

Ms Thomson has been linked with property deals involving Christopher Hales, a solicitor who was struck off by the Scottish Solicitors' Disciplinary Tribunal (SSDT) in May last year in connection with 13 transactions in 2010 and 2011.

Prosecutors have instructed police to carry out an investigation into ''alleged irregularities'' relating to property deals in the year 2010/11 after the case was referred to the Crown Office by the Law Society of Scotland.

The society said concerns over potential criminal matters relating to the tribunal's findings were first raised ''informally'' with the Crown Office in December 2014, and then ''formally'' in July this year.
