Every time I visit Iraq or Afghanistan I am blown away.

I'll be explaining that Britain will be leaving the European Union, but I want that process to be as constructive as possible. And I hope the outcome can be as constructive as possible because of course while we're leaving the European Union, we mustn't be turning our backs on Europe.

I want the European Union to be a success. And I want a relationship between Britain and the EU that keeps us in it.

Britain is characterised not just by its independence but, above all, by its openness. We have always been a country that reaches out. That turns its face to the world.

We are a great country, and whatever choice we make we will still be great. But I believe the choice is between being an even greater Britain inside a reformed EU or a great leap into the unknown.

Over the longer term, the institutions and powers of the EU will continue to expand and certain policymaking powers, heretofore vested in the member states, will be delegated or transferred to, or pooled and shared with EU institutions. As a result, the sovereignty of the member states will increasingly be eroded.

The news that Osama Bin Laden is dead will bring great relief to people across the world. Osama Bin Laden was responsible for the worst terrorist atrocities the world has seen - for 9/11 and for so many attacks, which have cost thousands of lives, many of them British.
