Video footage has emerged that appears to show Liam Fox and his close friend Adam Werritty at a meeting with the Sri Lankan president last year.
It comes as the defence secretary is facing a Ministry of Defence inquiry into his working relationship with Mr Werritty, who has no official role.
The video purports to depict a meeting Mr Fox had with Sri Lankan president Mahinda Rajapaksa in a London hotel last year.
The MoD said the meeting had been a private one and no special advisers had been in attendance.
