A world record crowd for a club rugby match of almost 84 thousand turned up to watch English Premiership leaders Harlequins beat London rivals Saracens 24-19 at Wembley Stadium.
The previous record was just over 82 thousand for a 2009 Heineken Cup quarter-final between Leinster and Munster at Croke Park in Dublin.
Harlequins and Saracens attracted a crowd of 82,000 earlier this season at Twickenham.
