The Aviva Premiership Rugby clash between Saracens and Harlequins at Wembley set a new world record attendance for a club rugby match of 83,671.
The bumper crowd beats the previous world record of 82,208 fans that watched the Leinster versus Munster Heineken Cup semi-final in May 2009 as well as topping the recent Aviva Premiership record attendance of 82,000 at the Harlequins vs Saracens league fixture in December 2011.
Commenting on the new world record, Nigel Wray, Saracens' chairman, said: "Everyone at the club is delighted with this record-breaking crowd and I'd like to pay tribute to the huge team who brought this wonderful day together.
"Seeing so many rugby supporters at Wembley, enjoying a great family occasion, certainly made me feel very proud."
The innovative London club has worked closely with sponsors on the fixture including Premiership Rugby's title sponsor's Aviva, to promote the top-of-the-table clash that also saw a host of additional entertainment, including performances by chart topping band McFly, who played both before kick-off and at half-time.
"These Wembley games have proven to be a great success with supporters," said Kevin Peake, Director of Brand, Sponsorship & CR at league title sponsors' Aviva.
"As well as being able to watch the most exciting and competitive club rugby anywhere in the world, the high profile venue, music acts and other entertainment have clearly helped to attract a much broader audience than simply rugby fans."
