Liam Fox faces fresh allegations over best man

Defence Secretary Liam Fox has arrived on a visit to Libya amid further claims about his working relationship with his best man, Adam Werritty.

It has emerged Mr Werritty set up a meeting for Dr Fox with businessmen in Dubai, despite having no official role.

On Friday, Dr Fox ordered a Ministry of Defence inquiry into whether their relationship had breached security or the ministerial code.

Labour called on Dr Fox to answer questions directly.
