Voters will be going to the polls fully informed on Corbyn

Even so, the Labour Party leader and possible prime minister – if recent opinion polls are accurate – is placing ultimate responsibility for massacres at our own door.

His logic is that such a suicide bomb is indefensible, but that it would not be happening if it had not been for UK participation in the ‘war on terror’.

Among the many critics of Mr Corbyn’s speech, the Tory security minister Ben Wallace has described the comments as were “totally inappropriate and crassly timed.”

But the comments are nonetheless welcome, because they mean that more and more voters are becoming aware of Mr Corbyn’s world view. Many voters will still not know that Mr Corbyn is a long-time radical who has given a platform to extremist pro terrorist groups since the day he was elected to the House of Commons in 1983.

Just last week he was unable – simply unable – to bring himself in a TV interview to condemn IRA terror, falling back repeatedly on his condemnation of “all bombings”.

This man, who stands within reach of 10 Downing Street, perhaps at the helm of a coalition (if Theresa May fails to win an overall majority), seems to think that Britain and the IRA were equally at fault in Northern Ireland.

His position was later clarified via a party spokesman but not in his own quotes. There is, in fact, still the sense that he thinks British soldiers were no better than IRA terrorists. His latest comments after Manchester suggest he thinks the state is more culpable for Islamic violence.

Mr Corbyn has made clear that he will be a tax (heavily)and spend (even more heavily) prime minister.

Now he is making clear his approach to national security.

Voters cannot say they are going to the polls uninformed.
