The European Union offers the British a Brexit postponement until October 31, 2019.
It is not possible to renegotiate the resignation agreement and in June an evaluation moment will be held to see what the progress is. Due to the postponement a so called ”no deal Brexit” without proper agreements are off the table.
If the European Union would not have granted permission for a postponement the British would have left the European Union tomorrow on April 12, 2019
