Cameron quits: Eight things that defined ex-PM
Mr Cameron's time in politics was dominated by referendums - he won two but the third ultimately ended his political career.

A few months ago, most of us expected David Cameron to still be Prime Minister, and of course an MP - but soon he will be neither.
As he prepares to turn 50 next month, here are eight things we will remember about the stockbroker's son who became the youngest PM for almost 200 years.
:: Referendums
With three referendums, Mr Cameron gambled three times but won only two.
The AV referendum was part of his deal with the Liberal Democrats and one he was unlikely to lose.
Not true of Scotland - at one stage a poll put the nationalists in the lead. But Mr Cameron won, allowing him to claim he helped save the Union.
But his biggest gamble on our membership of the EU failed, it lead to his downfall as Prime Minister and his resignation as an MP.
:: Coalition
Mr Cameron failed to win an overall majority in 2010 - extraordinary in some ways after 13 years of Labour rule.
But his failure did lead to him entering into government with the Liberal Democrats, becoming the first post-war coalition Prime Minister.
Despite early predictions of a quick collapse, the coalition managed to last the entire five-year term.
:: Cameron's Conservatism
Mr Cameron's conservatism was initially defined as "compassionate conservatism" in the vein of one-nation conservatism.
"Hug a hoodie", his trip with huskies in the North Pole and his defence of NHS spending seemed to set him apart from previous leaders.
However, critics accused him of slashing welfare, leading to a rise in use of food banks and increasing inequality.
:: Foreign Interventions
Despite war fatigue following Iraq and Afghanistan, Mr Cameron proved an interventionist leader.
First, the Libya conflict brought about the death of Colonel Gaddafi but also the collapse of the country.
Mr Cameron wanted a similar intervention early in the Syrian war but lost an initial vote in Parliament. He managed to convince MPs in a second attempt last year.
:: Chillaxing Cameron
Mr Cameron always seemed able to separate work from his professional life, with reports of a man who liked playing tennis, a glass of wine and a sing song on his personal karaoke machine.
:: Cameron The Family Man
Mr Cameron was very much a family man, a father to two sons and two daughters.
He has spoken of his grief and pain at the death of his eldest son Ivan.
Ivan, who was severely disabled, died in 2009 at the age of six.
:: Cameron The Conservative
Mr Cameron often had an uneasy relationship with the right of the party. Many didn't like his brand of Conservatism and he didn't like them in return.
Two of his MPs, Douglas Carswell and Mark Reckless quit to join UKIP.
That, along with internal pressure from eurosceptic MPs, forced Mr Cameron to call the EU referendum.
:: Cameron's Cock-Ups
Where to start?
From having to apologise for telling Labour's Angela Eagle to "calm down dear" at PMQs, to saying he was embarrassed and sorry after being overheard saying the Queen purred down the phone at him.
He couldn't remember his football team was Aston Villa during the election campaign and recently branded a number countries as corrupt just ahead of a sensitive summit on the subject.
And after more than 15 years as an MP, Mr Cameron's final gamble on Britain voting to stay in the EU has led to him stepping off the political stage completely.
