AMID the relentless doom, gloom and incessant debating of Brexit, there are some moments of pure “you couldn’t make it up” comedy.

Last week’s laugh-out-loud moment was brought to us courtesy of the BBC when, as Sophie Raworth recapped the main story of the day - that prime minster Theresa May was heading back to Brussels for more talks with the EU - grainy, black and white footage of Battle of Britain planes in action during the Second World War was flashed across our screens.

The BBC put the mix-up down to “human error” but as an unintentional visual metaphor it was an inspired piece of broadcasting.

It is to be assumed that Mrs May was not accompanied to Brussels by Bomber Command any more than she travelled there via Spitfure, dressed in a leather flying jacket and goggles - but the wartime analogies regarding Brexit have continued thick and fast.

This week’s Brexit nonsense, wheeled out in all seriousness, is the news that plans are afoot to evacuate the Royal Family from London in the event of rioting in the streets should we “crash out” of the EU without a deal.

The plans - initially drawn up during the Cold War - will see Her Majesty and her family spirited out of the capital to a secret venue.

Presumably, if indeed we do “crash out” without a deal (a phrase which only adds to the sense of impending doom - most sensible observers prefer the less hysterical version: leaving on World Trade Organisation terms), the rioting will be done by Remainers. I can’t imagine that there will be many Leavers donning face masks in order to take to the streets in protest about Brexit actually having happened.

This constant scare-mongering is beginning to suffer from the law of diminishing returns. The more the Brexit doomsters wring their hands and issue warnings about royal evacuees, Mars bars shortages and the need to stockpile everything the more we sensible Brits take it all with a huge pinch of (non-stockpiled) salt.

To return to the Second World War analogy, we’re a nation of make do and menders, those cliched Keep Calm and Carry On motifs actually do speak to our national psyche. If and when Brexit takes place - and if it’s a no-deal Brexit, which I think is unlikely - we will get through any initial (and probably short-lived) disruption.

We won’t be panic-buying lettuces and tomatoes any more than the Queen and Prince Philip will be holing up in a safe house like they’re on the witness protection scheme. If they do have to be evacuated though, for goodness sake don’t let Philip drive the removal van.
