He told Newsnight: “The real decisions will not be taken by Barnier but will be laid down by the Brexit committee chaired by Theresa May. From the EU, Angela Merkel and Francois Hollande will have a culpable role.”
Sir Malcolm revealed he had disagreements with Barnier while he was French foreign minister and said he was a “strong European federalist”.
He added: “He is a tough guy and a strong European federalist by background. Being French he has a strong protectionist streak, he is not very keen on free trade and open borders.”
