EU Commission President Jean Claude Junker has appointed Michel Barnier, a former EU Commissioner for the Internal Market as the EU Commission's chief Brexit negotiator. The Frenchman was responsible for the introduction of a significant amount of the EU regulations on financial services following the euro-zone crisis. Despite the announcement that Mr Barnier will take up his role on 1 October 2016, it is expected that the negotiation positions will first be agreed at a political level by the EU Council.
