Somerset skipper Justin Langer receives the Division Two trophy

Leg-spinner Michael Munday claimed a career-best 8-55 as Somerset secured an innings victory over Nottinghamshire.

He added two wickets to his overnight figures as Notts, resuming on 147-7, were all out for 190 on day three.

Paul Franks offered resistance but went for 30, bowled by Ian Blackwell, as play was wrapped up before lunch.

As Somerset were already Division Two champions, there was little to play for once Notts took a day-one bowling point which ensured their own promotion.

Munday, who had never taken more than three wickets in a Championship innings before, beat his previous first-class best of 6-77, which was recorded for Oxford University in the 2006 varsity match.

His final wicket was that of Jason Gallian, caught at cover for 14 after coming in at number 10 because of a back problem.

Somerset, who were presented with the Division Two trophy after the match, amassed a record 266 points, beating Surrey's 262, achieved last season.

Michael Munday...could be the x factor in helping us win the championship title next season Marcus Trescothick

"I have played with England and won quite a number of things, but to actually win a trophy in front of your own home crowd is a really special occasion.

"You live in the town and know a lot of people who come to watch the cricket, so it is a really momentous for everyone, for the whole of Taunton," batsman Marcus Trescothick told the official Somerset website.

"I think the way we won this game is testament to the way that we have played our cricket this year. Michael Munday has played brilliantly for us in this game and Justin [Langer] is right when he says he could be the x factor in helping us win the championship title next season.

"If he bowls anything like he has in this game, then we have got a real good chance, especially if we can keep Andy Caddick and Charl Willoughby fit as well."
