If Europe is now at a crossroads, if we opt to stay inside the EU, it is clear that the Treaty on European Union's article 1 commitment to ‘ever closer union’ will surely leave the UK with even less influence than it currently has. Leaving the EU would give us greater influence on a global level.
The government would also be free to push for new global trade deals, and reinforce its links with the Commonwealth.
As an English speaking nation, a major economy with vast resources in research and innovation, not to mention cultural output, there is a lot the UK can gain from engaging more fundamentally with the rest of the world, and vice-versa.
We believe it would be better to exercise our own voice on a global level than be an increasingly marginalised voice within the EU.
