Scotland has voted No to independence in a referendum, meaning its 300-year old union with the UK will continue. So how did the No campaign win?

1. They were always the favourites
The No camp had a head start. When the Edinburgh Agreement was signed on 15 October 2012, paving the way for a referendum in 2014, polls suggested about a third of Scotland's 4.2m voters wanted independence.
A plethora of polls over the next 18 months consistently put the No camp ahead.
In June - by which time there had been 65 opinion polls - all bar one had put the No side in the lead, according to polling expert Professor John Curtice.
"The No side were always favourites to win, which is why the YouGov poll for the Sunday Times which put the Yes vote ahead about 10 days ago created such an upset," he says.
Happily for the No side, most of the following polls put them back in the lead again and they were able to finish ahead of the underdogs on polling day.

2. The Scottish feel British
A resurgence of Britishness - either caused by, or coinciding with the referendum - is credited with giving the pro-union No campaign a boost.
The number of people living in Scotland who chose British as their national identity rose from 15% in 2011 to 23% in 2014, according to the Scottish Social Attitudes Survey. The number of people who chose Scottish fell from 75% to 65% over the same period.
However, there is also evidence that the rising tide of British sentiment in Scotland has taken place over a longer timescale.
Almost one third of Scots now say they are "equally Scottish and British" - the highest proportion since former Labour PM Tony Blair came to office in 1997, according to the survey. Less than one in four describe themselves as "Scottish not British".
"At the end of the day, Scotland still feels moderately British," says Prof Curtice.

3. The risk factor
The No campaign came under fire from the Yes campaign for being negative, with some dubbing it "Project Fear".
However, the No vote suggests Better Together was successful in "drawing people back from the prospect of taking a risk that was not necessary," according to Prof Curtice. Just two days ahead of the polls, voters were twice as likely (49%) to regard independence as a risk than staying in the Union (25%), he says.
In April, Scotland's First Minster Alex Salmond called the No campaign "the most miserable, negative, depressing and thoroughly boring" in modern times. In contrast, he said the "Yes" campaign was "positive, uplifting and hopeful".
More recently the leader of the SNP criticised the "scaremongering" of No, saying the Yes side was "determined to focus on opportunity".
The Better Together campaign always denied being too negative, saying the campaign was a positive one, emphasising what the union had achieved with Scotland in it, and how much more could be done when the UK "stands together".
However, it often accused Mr Salmond of not giving answers, with Mr Darling saying voters were "very alive to the risks" and uncertainty of independence.
Earlier this week, UK Prime Minister David Cameron told Scottish voters it was his "duty" to warn them of the stark costs of a "painful divorce".
