Mr Coburn said “demands” for a multi-billion pound Brexit divorce bill by European Union chiefs were due to “necessity” because the Brussels bloc was “broke”.
Speaking in the European Parliament in Strasbourg, the leader of Ukip in Scotland sparred with German MEP Elmar Brok, who said the EU was not a “golf club” that the UK could just leave.
Mr Coburn said: “Surely Mr Brok, it’s not a matter of ‘right’ that the European Union demands this money, it’s a matter of necessity, would you not agree with me?
“Because you are broke.”
