Britain is a country where old men know that, until their time runs out and sure of their cause, they must continue to oppose Brexit

In these dark days it is time to reprise the spirit of the article Will Hutton wrote in the Guardian this time last year : 

In it he reminded readers that : 'Remain Britain – half the population – has no champion.' However, he said that : 'Brexit must be opposed in every dimension. This is a Conservative project. The Tories must be its sole sponsor and live with the consequences. I think it will break them.'

He ended by suggesting that :
'So at 11pm on 31 January, dismiss Johnson’s extravagant claims for what lies ahead and the faux celebrations. Light a candle in a window, at your door, in your garden; find friends to do it together. We stand for a European Britain. We will be back.'

Although Old Men know that it is unlikely that they will not see Britain rejoin Europe in their lifetimes, in their continued opposition to the anathema, they can take heart from the words of Prime Minister Winston Churchill, who said in 1941, in the darkest days of the Second World War : 

"You cannot tell from appearances how things will go. Sometimes imagination makes things out far worse than they are; yet without imagination not much can be done. Those people who are imaginative see many more dangers than perhaps exist; certainly many more than will happen; but then they must also pray to be given that extra courage to carry this far-reaching imagination. But for everyone, surely, what we have gone through in this period - 
this is the lesson: never give in, never give in, never, never, never, never - in nothing, great or small, large or petty - never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy."
