There will not be a delay past July, it's either no deal and they pull the plug on business cycle or extension until July 1st for no deal preparations... I think the whole idea initially was for May to sabotage Brexit, but she couldn't pull that off and EU leaders have grown tired of far right activists in UK, they want them out... They are viewed as cancer and trying to break up the EU
Look at videos from EU figures or what they say, the shift in the past week is completely different then from few months ago, they believed May could get them to another Referendum which stay would of won by a long shot, she failed... They have now accepted it, and rather move on and have UK-Norway type relationship then have this dragging on, having Tommy Robinson or Farage in EU Parliament is a nightmare for them it seems... It's a complete 360 from the initial sabotage plan May had, what's been unfolding has practically been a guarantee the UK leaves EU now, one way or another... The Eurosceptics made sure of it
