The Prime Minister will make regaining control of Britain’s borders one of the central themes of her Brexit strategy and will also make clear that the rights of UK expats will be protected.

She will make clear for the first time that Britain will not seek a watered down version of Brexit, something that Remain campaigners are still pushing for.

The Prime Minister will say that Britain is quitting the single market and although she will be less explicit on the issue of the customs union, her remarks will make clear that after Brexit the UK will no longer be a member.
