‘Theresa May will ask European leaders to delay Brexit after John Bercow’s bombshell intervention plunged Britain into a “constitutional crisis”, Downing Street has confirmed.
‘Following a prolonged Cabinet meeting this morning, the Prime Minister’s official spokesman said she would now write to Donald Tusk “in relation to an extension”.
‘Whilst they refused to say how long a delay she would request, it is understood that Mrs May will ask for an extension running until 30 June, which could be extended if a deal has still not been ratified by Parliament…’
That date fits closely with previous post prophecies regarding 9 months October 2018 to July 2019 delay -see Fear Not – Watch Next 4 Months.
