Boris Johnson is adamant that our ties to the EU must end on December 31.
And tomorrow he will make clear he is prepared to sign up to a lesser trade deal than the one Canada enjoys to do it.
We hope this is only the opening salvo in tricky negotiations ahead. A blustering PM making a show of playing hardball.
And we hope the EU and UK will ultimately come to an agreement that suits us both.
That is because the Sunday Mirror wants Brexit to be a success.
True, we backed Remain in the 2016 referendum. True, we kicked against the duff deals struck with Brussels by Mr Johnson last year, and Theresa May before him.

But we have always respected the result of the referendum. And the verdict of the voters at the General Election confirmed that most wanted to go ahead with leaving Europe.
Now it is time for all of us to pull together and give Britain’s journey into the post-Brexit world our best shot.
The United Kingdom can achieve much as a united nation, which is why the Brexit arguments which divided us must now be over.
As Boris Johnson said, this is not the beginning of the end. Just the beginning of the beginning. Let us face it as one.

Load of hot heir
Prince Charles was warning about the dangers of climate change long before Greta Thunberg was even a twinkle in her parents’ eyes.
He quite rightly used his position to highlight the damage we were doing to our environment.
But as he knows better than anyone, his position brings with it an onerous responsibility.
And he must take responsibility for his own travel arrangements.
Today we reveal how Charles caused 2.5 tonnes of carbon emissions by taking copter flights to an event at which he urged scientists “to rescue this poor old planet”.

We understand there are time and security constraints on the heir to the throne. We suspect Charles probably does much to offset his own carbon footprint.
But now he must remind those who organise his movements they must think about the planet too.
Cuffs and scuffs
When it comes to hurting themselves, our police are more like the Keystone Cops than the Sweeney.
Some scalded themselves on their tea, others were burned by microwave meals, and three Met officers injured themselves while ironing uniforms.
So if you’re embarking on a criminal career, you’ll find all the tools you need to beat justice... in your kitchen.
