Tory chairman Feldman a witness in bullying row inquiry
The Tories have confirmed party chairman Lord Feldman is being interviewed as a witness as part of an inquiry into the handling of bullying and blackmail allegations.
The row over alleged behaviour by Mark Clarke shows little sign of abating despite the resignation of international development minister Grant Shapps, who said he believed the "buck should stop with me".
The departures of Mr Shapps and Lord Feldman had been demanded by the father of a Conservative Party activist who killed himself, leaving a note condemning Mr Clarke - who denies any wrongdoing.
The final straw for Mr Shapps appears to have been the emergence of an email sent to him by ex-minister Baroness Warsi in January, complaining that the election campaign aide had been abusing her on Twitter.
The party had insisted no complaints against Mr Clarke, who ran its RoadTrip canvassing drive in the run-up to the election, were received before August.
