Sources close to Tory leader say Jack Ross, who faces party investigation after undercover report, worked as social media consultant

A former Conservative election candidate who was suspended after he was filmed discussing the cost of hiring contract killers worked as a consultant in Kemi Badenoch’s office as recently as last year.

Jack Ross is facing an investigation by the Tories after he was filmed apparently asking an undercover reporter: “What do you want done?” and apparently offering to “broker” the services of an alleged far-right paramilitary group.
