London terror attack

Theresa May fails the London Terror test

When a British Prime Minister three days before a general election faces a call to resign, and the opposition leader who makes the call is not heaped with ridicule by the whole country and the media, then something for that Prime Minister has gone seriously wrong.  That is the situation Theresa May faces today.
The proximate cause is the London terror attack, with Labour leader Jeremy Corbyn criticising Prime Minister for cutting police numbers whilst Home Secretary despite the rising threat from ISIS, and claiming that this has exposed Britain to terrorist attacks.
