Here is Prime Minister David Cameron’s speech following Britain’s vote to leave the European Union in full:
“Good morning everyone, the country has just taken part in a giant democratic exercise, perhaps the biggest in our history.
Over 33 million people from England, Scotland, Wales, Northern Ireland and Gibraltar have all had their say.
We should be proud of the fact that in these islands we trust the people for these big decisions.
We not only have a parliamentary democracy, but on questions about the arrangements for how we’ve governed there are times when it is right to ask the people themselves and that is what we have done.
The British people have voted to leave the European Union and their will must be respected.
I want to thank everyone who took part in the campaign on my side of the argument, including all those who put aside party differences to speak in what they believe was the national interest and let me congratulate all those who took part in the Leave campaign for the spirited and passionate case that they made.
The will of the British people is an instruction that must be delivered.
It was not a decision that was taken lightly, not least because so many things were said by so many different organisations about the significance of this decision.

So there can be no doubt about the result.
Across the world people have been watching the choice that Britain has made.
I would reassure those markets and investors that Britain’s economy is fundamentally strong and I would also reassure Britons living in European countries and European citizens living here there will be no immediate changes in your circumstances.
There will be no initial change in the way our people can travel, in the way our goods can move or the way our services can be sold.
We must now prepare for a negotiation with the European Union.
This will need to involve the full engagement of the Scottish, Welsh and Northern Ireland governments to ensure that the interests of all parts of our United Kingdom are protected and advanced.
But above all this will require strong, determined and committed leadership.
I’m very proud and very honoured to have been Prime Minister of this country for six years.
I believe we’ve made great steps, with more people in work than ever before in our history, with reforms to welfare and education, increasing people’s life chances, building a bigger and stronger society, keeping our promises to the poorest people in the world and enabling those who love each other to get married whatever their sexuality, but above all restoring Britain’s economic strength.
And I’m grateful to everyone who’s helped to make that happen.
I have also always believed that we have to confront big decisions, not duck them.
That is why we delivered the first coalition government in 70 years, to bring our economy back from the brink.
It’s why we delivered a fair, legal and decisive referendum in Scotland.
And it’s why I made the pledge to renegotiate Britain’s position in the European Union and to hold the referendum on our membership and have carried those things out.
I fought this campaign in the only way I know how, which is to say directly and passionately what I think and feel - head, heart and soul.
I held nothing back, I was absolutely clear about my belief that Britain is stronger, safer and better off inside the European Union and I made clear the referendum was about this and this alone - not the future of any single politician including myself.
But the British people have made a very clear decision to take a different path and as such I think the country requires fresh leadership to take it in this direction.
I will do everything I can as Prime Minister to steady the ship over the coming weeks and months but I do not think it would be right for me to try to be the captain that steers our country to its next destination.
This is not a decision I’ve taken lightly but I do believe it’s in the national interest to have a period of stability and then the new leadership required.
There is no need for a precise timetable today but in my view we should aim to have a new prime minister in place by the start of the Conservative Party conference in October.
Delivering stability will be important and I will continue in post as Prime Minister with my Cabinet for the next three months.
