Huawei will be a test of whether Boris Johnson really is going to take back control

But anything short of sticking entirely by May’s decision will be a resounding confirmation that Britain has traded servitude to Brussels for abasement to Washington

The medical advice coming from China right now is not to stockpile antiretrovirals. Then again, you might want to be ordering some antiemetics. Because if you had thought that Brexit Day would be the most nauseating of the coming days, think again.

By the time Big Ben hasn’t bonged on Friday night, Boris Johnson is scheduled to announce whether or not Chinese telecoms goliath Huawei will continue to play a central part in the UK’s nascent 5G network.

It isn’t Boris’s decision alone. By that, I make no reference to “cabinet government” – a more mythical beast than ever with this cabinet of none of the talents, and Johnson reportedly sharpening his axe. I refer, of course, to the president in a pushchair masquerading as a golf buggy.
