Tomorrow we are leaving the European Union’s customs union and the single market. For so many of us, this is a moment of great sadness. Nothing has happened since the referendum to make one think that this is anything other than a historic error.

In the face of tomorrow's events, I remain proud of who we are as Europeans and what we stand for. We must not let Boris Johnson define who we are.

I am proud to call myself a European. It is not just a phrase, but a statement of intent. When we call ourselves European, we reject the narrow confines of Boris Johnson’s nationalism and commit to building something better. We will continue to build a larger, unified and powerful community of interests to fight for Britain’s future in Europe.

We may be leaving the European Union tomorrow, but you can still help build the European community of the future. The European Movement is already the largest pro-European grassroots organisation in Europe, but if we are going to win this fight for our European values, we need an even bigger movement.

Today, I am asking pro-Europeans in the UK to join us and work with us to rebuild our relationship with Europe.
