BORIS Johnson is to publish a review outlining its plans for a "more prosperous and resilient Union" in 2030.

The 100-page document will emphasise the strength of the Union in driving the UK's foreign policy success, despite more than 20 polls showing a majority support Scottish independence.

The Integrated Review, which has been conducted over the last year, addresses national security, foreign policy and the UK's approach to the global economy.

The plans include building ships in Scotland and armoured vehicles in Wales. Trade hubs will be also be established in Wales and Northern Ireland, in addition to the one currently in Scotland.

A statement about the document said: "Scottish capabilities – in space, cyber and maritime industries – contribute immensely to the security of our shared nation.

"And the people of Scotland contribute hugely to our international policy: from the 10,000 regular military personnel and 4000 reservists call Scotland home to the 1500 diplomatic experts who will be based in the Foreign Office’s East Kilbride HQ after a huge expansion to their operations north of the border.

"There are three fundamental national interests that bind together citizens in all parts of the UK: sovereignty, security and prosperity."

Setting out the conclusions of the Integrated Review, the Prime Minister will say: “I am profoundly optimistic about the UK’s place in the world and our ability to seize the opportunities ahead.

“The ingenuity of our citizens and the strength of our Union will combine with our international partnerships, modernised Armed Forces and a new green agenda, enabling us to look forward with confidence as we shape the world of the future.”

The SNP has said a vote will be held in the next parliament if the party secures a May majority.

Until this month pollsters had recorded 22 consecutive polls showing a majority of Scots support leaving the Union.

Scottish Secretary Alister Jack said: "I welcome the publication of the Integrated Review and the UK Government’s vision for a modern defence, security, foreign and development policy, to tackle the threats of the 21st century as one United Kingdom.

"Scotland has a huge role to play in building a stronger, more secure, more prosperous and resilient Union and I'm proud that Scottish capabilities – in defence, space, cyber and maritime industries – will continue to contribute immensely to the security of our shared UK."

The plans will also aim to tackle climate change and preserving biodiversity, as well as devoting 2.4% of GDP by 2027 to research and development in the science industry.

The Telegraph reported last week that Johnson and other senior Tories are engaged in ongoing discussions of how to combat independence support.

Among them is Commons Leader Jacob Rees-Mogg’s idea to see the House of Commons sit in the Scottish, Welsh and Northern Irish parliaments for a fortnight every year. MPs would gather in Holyrood, the Senedd or Stormont with the location changing each year. This would happen in September, when the Commons returns from summer recess.

A source said this idea would “bring Parliament closer to the people”. There are concerns over the costs and Commons Speaker Lindsay Hoyle is not convinced by the idea.

On a practical level there are 650 MPs and devolved parliaments would struggle to accommodate them all.

The devolved administrations’ consent would be required to set up the system, which seems unlikely given the struggling relationships on show currently.

The SNP’s longest-serving MP, Pete Wishart, said the idea showed that the Tories’ arrogance “literally knows no bounds” due to the Scottish Parliament sitting in September.

The idea is just one of the many proposals for preserving the Union which the Tories are taking into active consideration.

When Michael Gove and Alister Jack want to talk through ideas to prevent Scottish independence, they do so over a cigarette “literally by the bike sheds”, a source told The Telegraph.

It is understood Downing Street’s current short-term plan revolves around arguing now isn’t the time for another referendum given the ongoing public health crisis.

The UK’s Cabinet Office will also be setting up a second headquarters in Glasgow in further efforts to strengthen the Union.

Gove, the current Minister for the Cabinet Office, will be visiting the city this week as part of the plan to reinforce the UK Government’s “commitment” to Scotland.
