In less than a year the Conservative and Unionist Party will face a threat to its existence.

Maybe not the Conservative bit, but certainly the Unionist portion. Coming down the tracks are the Scottish election and a renewed Nicola Sturgeon is positioning herself and her party to rip apart the United Kingdom.

Unionists need to offer something better. Something bigger than Scotland, frankly bigger than Britain. That offer should be Canzuk.

Time is running out. The polls are going in the nationalists’ favour. Poll after poll, in fact, shows that the Union is on the back foot. We know what Nicola Sturgeon is likely to spin Scottish independence as being natural, inevitable, and the sensible option.

Far from being shown up by a pandemic that has hit Scotland hard, Sturgeon is buttressed by an impression of strength and a compliant media north of the border, and no scrutiny south of it.

The First Minister, using all the privilege that position entails, is going to cast independence as both normal, and a reprieve from chaos. Set Scotland free with Sturgeon, or risk being bound to Brexit Britain with Boris. Tories should understand the danger of this messaging, the party used it with great success against Ed Miliband in 2015.

What worries me is that, while there may be plenty of policies on offer, there is a lack of a narrative and a lack of an incentive for Scots to choose to stick with their fellow Brits in the years ahead.

My proposition to the leaders of the Conservative party then is simple. Use something popular, something bold, and something global to counter a proposition that would sow division, narrow Scotland’s worldview, and limit the freedoms of our people.

Offer them the world. Offer them the right to live and work right across Britain, Australia, Canada, and New Zealand. The North Atlantic and the South Pacific. A global alliance of modern, diverse, liberal, English-speaking democracies united by common cause, a shared head of state, institutions, businesses, academia, legal systems, and of course all important family links.

Scottish Nationalists look at the pandemic, some even at the possibility of manning the border and kicking out the Sassenach, and think their time has come. Tories should be telling them it has not, and that rather it is the hour of the Unionist instead.

For Unionists across all the Canzuk states are moving in tandem on this issue. Canzuk is now official policy of the Canadian Conservatives, it is the stated aim of the New Zealand First, ACT and National parties, and today we at the Adam Smith Institute launch a paper by Australian Senator James Paterson supporting the alliance.

His proposition should be studied carefully. New Zealand and Australia have a unique relationship in the same way that the United Kingdom does with Ireland. They treat each other with respect, understanding that lawmakers want the citizens of each to be safe and have high quality assured in the products they buy and services they procure. They recognise each other’s qualifications so teachers, and nurses, and engineers can work back and forth across the Tasman Sea.

If the EU weren’t trying to meld together ex-communist, ex-fascist, constitutional republics, monarchies, federal states and unitary government; if it weren’t pushing together 28 states with different languages and legal systems and centuries of mistrust and warmongering together, then they might try something similar. If Ireland weren’t in the EU we’d probably propose a similar idea across the whole of the British Isles.

We can, though, propose such a network between our high-trust English speaking allies. The ones with whom we share the Queen and who sit in the Five Eyes alliance. We already trust each other with the highest classified state secrets, we should be able to trust that Jenny from New Zealand can be a nurse talented enough to look after our Prime Minister without making her have to apply to have her qualification recognised.

Trust is what trade is all about, and you can trust your mates the most. We’ve fought and died together. No matter if you’re white, British Asian, Afro-Caribbean, or Cantonese, you’re likely to have family in one of the Canzuk states. In fact, 80 per cent more Brits live in CANZUK states than across the whole of the neighbouring EU, with 1.2 million Brits living in Australia alone.

Polls have consistently shown the idea is very favourably received in each of the states, with a recent poll for CANZUK International (based in Canada) showing supporting majorities in each with New Zealand highest (82 per cent in favour), followed by Canada (76 per cent), Australia (73 per cent) and UK (68 per cent). Over 300,000 people from the four states have signed a joint petition to encourage governments to commit to the idea.

Together these four states are emerging as a global force by sheer force of fact. Whether that’s challenging China over Hong Kong, or protecting the biodiversity of the oceans, or standing up for press freedom, we’re championing the liberal rules-based order that is the cornerstone of our prosperity on the global stage.

Our Canzuk states share a love for freedom, and it’s an offer that shines bright with opportunity and promise. A global future for a generation that has been disillusioned with a politics that has been inward looking. An idea that connects them to our shared civilisation, and to their own global families too.

Give Brits an offer they can’t refuse: give them Canzuk.
