Currie left the club at the end of the 1998 Super League season and was replaced by Dan Stains. In 1999, the club went one better in the Challenge Cup. Following a famous last-minute semi-final victory over Castleford, the Broncos reached the Challenge Cup Final at Wembley Stadium for the first time, but despite taking a shock early lead and performing bravely, they were soundly defeated 52–16 by red-hot favourites Leeds. The club returned to the Valley for the 2000 season, but sacked Stains after enduring a long losing streak. Tony Rea was appointed temporary joint head coach with Stains' assistant Les Kiss. Rea and Kiss managed to steer Broncos out of the slump. In 2000, the experienced John Monie was appointed Head Coach. Monie only stayed in the job until the last month of the 2000 Super League season with the club having had mediocre results during his tenure. Rea took over as caretaker coach until the end of the season and Broncos eventually reached mid-table security. Rea then resigned his Chief Executive role at the end of the 2000 season to become Head Coach on a full-time basis. York made an approach to the Virgin Group to buy the London Broncos in August 2001, with the aim of buying a Super League place for a proposed merged club to be based in York under a new name, York Wasps. This attempt was thrown out when Richard Branson rebuffed the offer as 'ridiculous, and speculative at best'. In 2002, fervent club supporter David Hughes purchased the majority shareholding from Virgin in a major restructuring of the club. The Broncos moved once again, to play their home matches at Griffin Park as tenants of Brentford FC. 2003 marked the club's first Super League playoff appearance, losing in the first round to St. Helens 24–6 at Knowsley Road. The 2005 season was marked by significant activity off the pitch as the club welcomed new chairman and majority shareholder Ian Lenagan who had bought 65% of the shares. This was followed by the announcement of a partnership with Harlequins Rugby Union Club that saw the club return to The Stoop Memorial Ground, this time formally renamed as Harlequins RL and adopting the host club's kit and crest for the 2006 season. 2006–2011: Harlequins Rugby League Ian Lenagan became the majority shareholder in the London Broncos in July 2005 and within a week
