Vadym Prystaiko, Ukraine's ambassador to the UK, told Trevor Phillips on Sunday that he "does believe" Britain's accusation that Vladimir Putin is plotting to install a pro-Moscow leader as head of the government in Ukraine.
He said: "I do believe that. It's not the first time they're trying to do so, historically, and in recent times."
Asked if Ukraine believes Mr Putin will invade, Mr Prystaiko pointed out there has been a Russian presence for almost eight years.
