Defence Secretary Liam Fox met his friends and former flatmate Adam Werritty "in the margins" of 18 overseas visits, he has told the House of Commons.
In a statement to the House, he also said Mr Werritty had visited him at the Ministry of Defence 22 times in the past 16 months, more than previously acknowledged.
Mr Fox said he would ensure that in future:
"Mr Werritty will not make private visits to the MOD... will not attend international conferences where I am present and will not meet socially abroad where I am on official business."
