The SNP has called for a “full, independent inquiry” into whether a Scottish Tory MP has broken the ministerial code.
David Duguid, who represents Banff and Buchan, reportedly criticised proposals for a windfall tax on energy company profits without declaring his wife's £50,000 shares in energy giants BP.
He had previously voted against proposals to examine the impact of increasing taxes on energy companies and has spoken out against potential windfall taxes on four separate occasions since 2022.
