They appeared to be on course for their target of 232 after Mark Ramprakash hit nine fours and a six in 72 in 64 balls and Mark Butcher added 62 from 88.

Wickets fell and 10 were needed in the final over from spinner Jigar Naik, but Matt Nicholson (57) hit a four and Dernbach swiped over long-off.

John Sadler made 62 off 68 balls for the Foxes and shared 105 with Tom New.

West Indian paceman Jerome Taylor removed openers Scott Newman and James Benning in the first five overs, and Ali Brown also fell cheaply, but the ever dependable Ramprakash and Butcher put Surrey back on track.

Australian tailender Nicholson then hit a flurry of boundaries, and though Naik collected three wickets, his last two overs cost a total of 28 runs.
