DUP sending signals to the Conservative parliamentary party?

This morning the Conservatives launched in Northern Ireland [what, again? – Ed] Yes, they’re NI Conservatives now rather than Conservatives NI. Now, where was I? Oh yes. There were a few names there, many of them former (unelected) supporters of the UCU-NF.

Yesterday however it was the DUP rather than the local Tories who caught the attention of Conservative Home when four of their number voted with Conservatives on a vote of no confidence (and against Labour and the Lib Dems).

Sending a message for the future?
