In a world of serious threats to the U.K. and to global stability, where we see violence and conflict pulling people back into poverty, international terrorism, migration crises, children dying from preventable diseases and global environmental concerns on the rise, Britain's leadership on the world stage is more important than ever.

I have long witnessed the enormous contribution Britain makes around the world, with our impact through multilateral as well as through our bilateral engagement.

The end of free movement means that we will be able to consider the impact on the existing labour market when determining whether we want unskilled workers from the E.U. to be able to come to the U.K.

Far from doing what it can to ensure that the companies and entrepreneurs of tomorrow are European, the E.U. actively stifles innovation.
