The Ford Focus ST driver set the timesheets alight after pro𒐪ducing a 1'33.670s lap around the Grand Prix layout. However, with the fastest time safely in his pocket, Cammish brought out the red-flag with around three-minutes to go after crashing out at the Old Hairpin.

Although it's unclear wh﷽at caused the crash, the incident caused significant damage to the rear of the Motorbase Performance prepared Ford Focus.

Despite his heavy crash, Cammish ended the s🦩ession over 0.4s clear ahead of the rest of the pack with Hyundai driver Tom Chilton proving 'best of the rest' after setting the se✨cond fastest time.

Championship leader Ash Sutton was third fastest aboar𒊎d the siste🐼r NAPA Racing UK, 0.016s ahead of leading Toyota effort Ricky Collard in fourth.

Having endured a nightmare weekend in Knockhill last time out, four-time champion Colin Turkington will be looking to reignite his fading ꧂title hopes after falling 81-points adrift of Sutton's championship lead.

Turkington ended the opening session as the fastest B✱MW runner in fifth ahead of Toyota Gazoo Racing UK's Rory Butcher in sixth.

Sam Osborne enjoyed a strong FP1 run to ensure three out of the four NAPA Racing Fords made the top-ten order in seventh, while Aron Taylor-Smith, Jake Hill and George Gamble completed the remainder of the top-ten FP1 order in eighth, ninth an🐈d tenth.

Elsewhere, defending champion Tom Ingram also endured a session to forget after the rear-left wheeꦜl vacated his Hyundai i30N towards the end of the session.
