I am deeply saddened at the result, which will reverse forty years of outward-looking, progressive collaboration with our neighbouring countries in the European Union we have built together. This is a dark day for Britain, and one whose painful impact will be felt across the country and abroad.
It has been a difficult fight, and of course we must now respect the decision that has been taken, albeit by the narrowest of margins, and following one of the most dishonest campaigns in political history.
The challenge that faces us is to find a way forward in the light of this decision, which can limit the damage both at home, in a country that is clearly deeply divided, and in our relationship with friends and allies around the world.
