The European Union has outlined its strategy for Brexit negotiations, suggesting talks on a trade deal could begin once sufficient progress is made on a separation settlement with the UK. The draft guidelines, issued by European Council President Donald Tusk, argue for a phased approach in talks. The draft will be sent to the 27 member states for approval. They will set the tone for two years of negotiations.<br/><br/>In a news conference in Malta today, Mr Tusk refused to start parallel talks on all issues at the same time, as suggested by some in the UK. He said, the framework for future relationship can be discussed only after achieving sufficient progress on the withdrawal . Mr Tusk added that while the talks would be difficult and complex, the EU would not pursue a punitive approach.<br/><br/>Britain formally triggered the Brexit process by sending the Article 50 notification letter to Mr Tusk on Wednesday. It had called for simultaneous talks on exit terms and future trade ties.
