Wrong have you ever considered that it isn't true?
"A spokeswoman for Angela Merkel rejected claims that most other leaders had been willing to sign an early reciprocal deal on migrants’ rights, stating there was “complete unanimity” that such negotiations could not take place until article 50 was triggered.
“The 27 heads of state have already made clear in their joint statement on 29 June 2016 – so immediately after the referendum – that participation in the single market goes hand in hand with all four freedoms of the single market, and on this question all member states are unanimous,” said the German chancellor’s spokeswoman, Ulrike Demmer. “There is also complete unanimity that there can be no pre-negotiations with Great Britain before notification.”
"The prevailing view among officials in Berlin is that even though Germany and Britain have roughly equivalent numbers of emigrants living in each other’s countries – and therefore a joint interest in securing their rights – agreeing on an early deal would be more easily said than done."
"Germany has denied it rebuffed an attempt by Theresa May to seal an early deal on citizens’ rights post-Brexit, and reiterated that there was “complete unanimity” among the EU’s 27 member states that the subject could only be discussed once Britain had triggered article 50."
"The Tory MP Peter Lilley told the Brexit select committee on Wednesday that Germany was one of the two countries the prime minister was referring to when she said in her Brexit speech on Tuesday she could not get full support from the 27 remaining member states for a deal on the rights of EU citizens in Britain and UK nationals on the continent."
Peter Lilley could be saying anything...... where is the proof?
The fact is that negotiations can only begin after a 50 is invoked.
