Political leaders are marking Brexit day with a series of speeches and statements setting out their hopes for Britain's future outside the European Union.
The First Minister will say that 'Wales remains a European nation' when he becomes the first of the politicians to make a speech this morning. He' is expected to say that "today is a day for looking forward, not back."
Everyone can agree leaving the European Union tonight is an historic turning point for our country. And that’s the theme I want to address today: the future.
Meanwhile the Prime Minister will make a TV address to the UK at 10pm, just an hour before Britain legally ceases to be a member of the EU.
In it, Boris Johnson is expected to say that his job is to "bring this country together and take us forward.
"The most important thing to say tonight is that this is not an end, but a beginning.
This is the moment when the dawn breaks and the curtain goes up on a new act. It is a moment of real national renewal and change. This is the dawn of a new era in which we no longer accept that your life chances – your family’s life chances – should depend on which part of the country you grow up in. This is the moment when we begin to unite and level up.
The Welsh Secretary, Simon Hart, will say that today makes the start of a move to "unleash the enormous potential of communities across Wales."
Today marks a new chapter in our history as we finally deliver on the decision made by the Welsh people and leave the EU. We are leaving as one United Kingdom with a mission to build better infrastructure, make our streets safer, clean up our environment and make our Union stronger. Together, we will unleash the enormous potential of communities across Wales.
