The party's business spokesperson withdraws amid a police probe.
A new SNP MP, Michelle Thomson, has voluntarily resigned the party whip. The police are investigating property deals she was involved in five years ago.
Michelle Thomson, MP for Edinburgh West, withdrew herself from the party whip and stepped down from her frontbench position when “alleged irregularities” emerged in a series of transactions enacted for her by her former solicitor, Christopher Hales, who was struck off.
The Telegraph reports that a spokesperson for the SNP said that the decision means that, in line with party rules, her party membership has also been suspended.
