Steffan Jones, the seam bowler, is leaving Derbyshire to return to his former county, Somerset, on a three-year contract for family reasons. Jones has enjoyed a successful season at Derby, taking 59 wickets so far, but rejected a new two-year deal.

Jones said: "I have had many sleepless nights in recent weeks over this decision and I have to point out that it is for purely family reasons. My wife Alex is expecting our first child and she is from Taunton and all her family are based there."

Jones played for Somerset from 1997-2003 before joining Northamptonshire for two seasons then moving north to Derby.
