Jim,
Liam Fox has announced that the matter of the Irish Border cannot be discussed until the E.U. trade deal is resolved
Ireland's Taoiseach Leo Varadkar has said that Ireland will veto any deal that does not guarantee open inland Irish borders.
Arlene Foster, whose party, thanks to a billion pound bribe, has announced that her party will never accept the establishment of a sea border between the Six Counties and mainland Britain.
A fine mess they have got us into - eh what!!

How can we discuss what kind of border to have until we know what restrictions might need to be enforced.
Britain will not put up border posts. If Ireland/EU want it they will have to supply it, man it and defend it. (An Irish gov. spokesman on R4Today said posts would be attacked by paramilitaries within a week.)

Britain would hardly miss Irish trade, but Ireland's economy depends on ours.
It is not us getting in a fine mess.
