Liam Fox's ties to friend Adam Werritty investigated

Defence Secretary Liam Fox has ordered an investigation into whether he broke the ministerial code over his working relationship with a close friend.

He has been accused of risking national security by giving best man Adam Werritty access to the MoD and allowing him to go on foreign trips with him, despite having no official role.

Mr Fox said he ordered the inquiry to clear up "baseless accusations". Ben Geoghegan reports.
