During a TV election debate last night, Prime Minister Theresa May attacked opposition leader Jeremy Corbyn by saying that he would not be prepared to drop nuclear weapons on the EU headquarters as part of the Brexit negotiations.
Corbyn responded by agreeing that he probably wouldn't but left enough doubt that he might.
Theresa May appears to have finally revealed her own Brexit strategy - to threaten the use of nuclear weapons if she doesn't get her way. It is a strategy which is unlikely to work.
The EU - or rather France - do have nuclear weapons of their own, so could respond to any threat with mutually assured destruction.
Boris Johnson later commented that it would be a glorious end to our EU membership to go out with a bang.
