A SCOTTISH Tory MP is being investigated by the Westminster standards watchdog.

David Duguid, a former Scotland office minister, is being probed amid concerns related to the declaration of an interest.

According to the Parliamentary Commissioner for Standards, the investigation into Duguid opened on November 27.

On the same day, a separate probe was opened into Marco Longhi, another Tory MP, amid concerns linked to registration of interests.

There are no details provided on either investigation other than which paragraph of the Code of Conduct the two MPs are being probed under.

Duguid (below) came under fire in July after reports revealed that he did not declare that his wife has more than £50,000 worth of shares in oil giant BP.

The National:

Duguid, the MP for Banff and Buchan, has spoken against windfall taxes on companies such as BP four times in parliament since the beginning of 2022.

The Guardian reported that an analysis of BP’s shareholder register suggests Duguid moved his shares into his wife’s name five years before he became an MP.

Parliamentary rules require MPs to declare the financial interests of family members and spouses where there could be considered a conflict of interest.

However, Duguid has never publicly disclosed his wife’s financial interest in the House of Commons register.

At the time, a spokesperson for Duguid insisted the MP had abided by the rules.

Since the start of 2022, the Tory MP has declared interest in BP in two debates in parliament, but only referencing his prior employment of 25 years in the oil and gas industry, 10 of which were spent working for BP.

The probe into Duguid is linked to paragraph six of the MPs’ Code of Conduct, which provides: “Members must always be open and frank in declaring any relevant interest in any proceeding of the House or its Committees, and in any communications with Ministers, Members, public officials or public office holders.”

The news comes after SNP Westminster leader Stephen Flynn avoided repercussions after a probe into whether he had misused parliamentary stationery concluded.
