A solicitor from Chorleywood has been drawn into row over controversial donations given to a senior cabinet minister.

Work and Pensions Secretary Peter Hain faces the possibility of a police investigation after it emerged last week that he failed to declare £103,000 in donations in his bid to become deputy leader of the Labour Party.

More than £26,000 of the money was channelled to Mr Hain through the Progressive Policies Forum (PPF), a company purporting to be a left-wing think tank.

However, in the 13 months since its incorporation in December 2006 the company has produced no reports and held no conferences.

Documents lodged at Companies House confirm that the organisation is a limited company, but only lists one shareholder - Gregory McEwen, of Chorleywood. Mr McEwen holds the company's single share, worth £1. His links to Mr Hain are unclear.

An investigation is currently being conducted by the Electoral Commission and the Parliamentary Standards Commissioner John Lyon.

Mr McEwen, of law firm McEwen Parkinson solicitors, has, so far, been unavailable for comment.
