Peter, Mr. Varadkar has played an excellent innings, doing what he is duty bound to do under the terms of the GFA....look after the interests of the Irish people, north and south.
Which is a darn sight more than can be said about the British government, which does not give one flg about the citizens of the region of the United Kingdom with most to lose from Brexit....Northern Ireland.
The majority of the people over there are opposed to leaving the EU.....they voted comfortably to Remain,
The majority of the people over there want the Backstop....they demonstrated that most emphatically at the European Election by returning two Remaim MEPs out of three.
So instead of the British government disregarding the wishes of the majority of people in NI and letting a miniority voice, the DUP, completely scuttle the sensible NI only Backstop May and Barnier agreed in November 2017, perhaps they could do the decent and correct thing and facilitate that arrangement.....which would also have the pleasant by- product for you and others of your ilk of actually have Great Britain leave the EU with a deal.
Northern Ireland is not Northern England....and the sooner the Brexit Brigade recognise that simple fact the better it will be for everyone, especially themselves.
In short, a Brexit for Great Britain is readily achievable.....a Brexit for the United Kingdom is a whole nother Brexit
