DURHAM moved back to the top of the table with their fifth win from seven games in the LV County Championship.

They will remain there if Middlesex fail to beat Yorkshire, while Somerset will be bottom once Hampshire have completed their victory against Sussex.

Paul Coughlin finished with figures of 10-6-10-4 and wicketkeeper Michael Richardson held five catches as Somerset succumbed for 158 to lose by 120 runs.

Tom Cooper was the first to go after lunch, although he clearly didn't agree with the caught behind decision which gave Graham Onions his third wicket.

Jim Allenby and Peter Trego did not look in too much difficulty in putting on 26, but then Allenby tried to hook a John Hastings bouncer and edged to Richardson.

After Trego played himself in quietly there was a shift in momentum in the 40th over as Onions' 13th of the innings cost 17 runs, including a no-ball.

Hastings had conceded only 14 in 12, but the next over produced 12 runs as Trego and Lewis Gregory began to go for their shots.

They were stymied by a double change, however, as the stand of 41 ended when Coughlin moved one sharply away from Gregory to give Richardson his fourth catch.

Alex Barrow survived only five balls before shuffling into a ball from Chris Rushworth which had him lbw for nought.

Trego fell for 35 in identical fashion to Gregory and it was all over when Tim Groenewald drove Coughlin to deep mid-off.
