I would ask:

If their neighbour was caught doing 120mph on the motorway would they go to court to defend him.

The answer of course would be an emphatical No, they would maintain that the neighbour had broken the law of the land and should be made the face the penalties laid down.

So, if they would not defend a neighbour who had broken the rules, why on earth do they do so when Johnson breaks the rules.

Simples really.

PS Steve, I have been told that this story about Johnson is old news because it goes back some days, the story about Corbyn goes back 4 years! Yet another example of the rank hypocrisy of some posters.
