An MP criticised windfall taxes on oil and gas companies, including BP, without declaring his wife's shares in the company, worth more than 50,000.

David Duguid, a former junior minister in the Scotland Office, has spoken out in parliament against windfall taxes on energy companies such as BP four times since the beginning of 2022. He has also voted against proposals to examine the impact of increasing such taxes. These levies could affect the size of the dividends paid to shareholders, as they would reduce the profits made by the companies, raising questions over a potential conflict of interest.
