a strife of interests masquerading as a contest of principles

So Iain Duncan Smith has resigned his post in Government. A charitable interpretation would be to believe his resignation letter that he could no longer go along with the cuts to disabled benefits. The more cynical might point at increased public attention to his own department's benefit cuts, or political maneuvering re Brexit.

May the whole lot of them boil in their own grease.

In fact, may the Government fall, and stay down and out. And then be refused benefits.
