Dan Cammish and NAPA Racing UK team-mate Dan Rowbottom traded blows during the opening Kwik Fit British Touring Car Championship Free Practice session at a damp Donington Park.

A steady start to the wet proceedings eventually burst into life when Cammish set a proper benchmark, which was soon bettered by stablemate Rowbottom. The #27 car of Cammish immediately responded, however, with his 1:41.679s lap time being good enough to secure P1.

Persistent light rain throughout the session meant lap times were particularly hard to look into, but it was clear that the NAPA Racing UK Ford Focuses were well set-up in the wet, with reigning champion Ash Sutton also riding high in fourth.

Team BRISTOL STREET MOTORS' Tom Ingram was best of the rest in third, but more than half a second off the pace, whilst the top six was rounded out by Árón Taylor-Smith (Evans Halshaw Power Maxed Racing) and Josh Cook (LKQ Euro Car Parts with SYNETIQ).

Tom Chilton was seventh in his #3 Team BRISTOL STREET MOTORS Hyundai, having led the way during the early running, whilst TOYOTA GAZOO Racing UK's Andrew Watson was next in the order.

The other two Toyotas in the field – Rob Huff (TOYOTA GAZOO Racing UK) and Aiden Moffat (LKQ Euro Car Parts with SYNETIQ) – both endured mixed sessions. Huff brought about the only red flag after going off in the early moments, whilst Moffat experienced the same fate at the Old Hairpin as the chequered flag waved.

Evans Halshaw Power Maxed Racing's Mikey Doble and Team BMW's Colin Turkington completed the top ten order.

The BTCC will be back on-track for FP2 at 1215, whilst qualifying will commence at 1505. Qualifying will be streamed LIVE via the ITV Sport YouTube channel.
