Nationalists in Northern Ireland are opposed to Brexit, and so will have little time for Johnson’s deal.  Unionists have no time for the deal, even though they support Brexit.

A December election in Northern Ireland could therefore turn, in a manner of speaking, into a referendum on the deal in which Ulster Says No.  Expect the DUP to make the most of the opportunity to get their vote back up.

It will argue that its MPs will seek to block the deal in the next Parliament. Loyalists are already rallying against it – on the ground that anything the Irish Government is for, they must themselves oppose.

In little more than a week, we have moved from hearing about potential violence and protest from Republicans to the same from Loyalists.  ConservativeHome is not at all sure that Downing Street is taking this into account.
