A highly intelligent top-order batsman, Smith signed for Middlesex for the 2005 season after an acrimonious departure from Kent.
A Cambridge University graduate, Smith combines his cricketing ability with a literary talent which has seen him write several books.
After a prolific county season, Smith made his Test debut for England in 2003 against the touring South Africans, making an elegant 64 in his first innings.
However, he was unable to build on that success and was not selected for the touring squads that winter. He has played three Tests for the full international side, to go with the three that he played for England Under-19 in 1996.
Smith recreated his run scoring antics in 2005 when he scored over 1,200 runs for Middlesex at an average of just under 40.
He enjoyed another productive season in 2006 and was named captain for 2007.
He again scored over 1,000 championship runs in 2007 - at an average of almost 51.
Smith endured a frustrating 2008, breaking his ankle mid-way through the season which saw him miss out on the Crusaders' Twenty20 Cup triumph and the Stanford Super Series.
Ed Joyce took over as captain before handing the responsibility to Shaun Udal who was appointed skipper on a full-time basis.
Smith announced his retirement from first-class cricket in November 2008.
