The moment GB won the Davis Cup
Great Britain have won the Davis Cup for the first time since 1936 after Andy Murray beat Belgium's David Goffin to clinch the decisive point in the final in Ghent.
Murray won 6-3 7-5 6-3 to give the visitors an unassailable 3-1 lead in the best-of-five tie.
Britain have now won the team title 10 times, while Murray adds the Davis Cup to his other major titles at Wimbledon, the US Open and the Olympic Games.
Captain Leon Smith guided Britain from the third tier to glory in five years.
Murray's monumental effort
Andy Murray has won 11 matches during Britain's triumphant 2015 campaign
Andy Murray has relished the team atmosphere ever since Smith, his childhood coach, took over as captain.
The world number two has insisted throughout that this is not a one-man team, and James Ward and Jamie Murray have contributed vital points during the winning campaign, but the younger Murray's achievement sets him apart.
The 28-year-old joins John McEnroe and Mats Wilander as the only men to have an 8-0 singles record in a Davis Cup year, and with the doubles he is only the fourth man to win 11 rubbers in a single year.
Murray also matches his contemporaries in winning one of the sport's biggest prizes, having won more points along the way than Novak Djokovic (seven points in Serbia's 2010 win), Roger Federer (seven points in Switzerland's 2014 win), and Rafael Nadal (six points in Spain's 2011 win).
Heavyweight Murray holds nerve in classic match
In another frenzied atmosphere at the Flanders Expo, Murray brushed off several early attempts to disrupt his service motion and set about stamping his class on the contest.
Goffin won just one game when the pair met in Paris earlier this month but already looked a much tougher proposition when he doubled that tally and saved an early break point.
Murray found himself under pressure at 2-2, facing a break point and more interruptions from the crowd, but he fired over a kicking second serve and shouted "come on" as the return flew out.
It heralded a spectacular few minutes of Murray at his best, a stunning forehand pass and two blistering returns helping him to break and another of those impossible winners taking him to 5-2.
Goffin played his way out of trouble impressively to save three set points on serve but Murray took his chance to close out the set with a forehand into the corner.
Strip away the prize on offer and the party in the stands, and the action on court was going as expected, with Murray the heavyweight to Goffin's middleweight.
The Belgian, ranked 16 in the world, fought well in the second set and gave his supporters reason to hope, but the pressure finally told in game 11 and a forehand found the net on break point.
Murray held his nerve from 0-30 to see it out, closing the set with another miraculous forehand from back on his heels, and when Goffin finally did break serve at the start of the third, the Scot hit straight back.
There was nothing more Goffin could do and Murray accelerated towards the finish line, breaking to love at 5-3 and then sealing victory on his second match point with a trademark backhand lob.
After wining the match, the rest of the British Davis Cup team raced on to the court to raise Murray above their heads and on to their shoulders
