Leason was registered as an entry in the Production Class for the 2003 Season, driving a ex-GR Motorsport Ford Focus for CMS Motorsport with support from MacMillan Cancer but this entry was delayed and ultimately never happened, he was also the test driver for a failed Super 2000 Ford Focus BTCC project in 2004.
He finally made his BTCC debut in 2006. He entered the last two meetings in a Vauxhall Astra Coupe run by Daniels Motorsport and previously driven by Andy Neate in the final meeting of the 2005 Season. He notably lost a wheel on his way to the grid at Silverstone.
For the 2007 Season, Leason was confirmed as a driver for BTC Racing in a Lexus teamed with Chris Stockton. He did not race at Croft that year[1] and after persistent reliability troubles he decided to abort his full season campaign. Leason achieved a final championship position of 24th.
In 2008, Leason announced that he planned to join up with Rick Kerry and Team AFM Racing to race a pair of diesel fuelled BMW 120ds,[2] though the team missed the whole season.[3]
Leason did eventually race the diesel powered BMW 120d in the opening four rounds of the 2009 BTCC[4] but withdrew due to lack of budget.
