A wily off-spinner by trade, Tredwell has become a key component in England's limited-overs sides.
He signed a full-time contract with Kent in 2002 and quickly established himself as a regular in all formats.
Also a useful lower-order batsman, he helped Kent to championship promotion in 2009, taking 69 first-class wickets, and was rewarded with an England call-up as cover for Graeme Swann on the tour of South Africa.
Swann recovered from injury to deny Tredwell an international debut, but both featured in the final Test of the Bangladesh tour when the Kent man took six wickets in a series-sealing win.
He enjoyed another solid domestic season in 2010 and was selected in England's 15-man squad for the 2011 World Cup, featuring in two matches and taking 4-48 from 10 overs against West Indies.
Tredwell returned to the England Test fold the following year in Sri Lanka, although he did not play and had to wait for more than a year for his next international appearance, in an ODI versus Australia.
He was named Kent captain for the 2013 season, replacing Rob Key, and made four England appearances during the 2013 Champions Trophy, taking 3-19 against South Africa in the semi-final.
With Swann rested, Tredwell was named England's primary spinner for the NatWest Series against Australia and when the Nottinghamshire off-spinner retired, Tredwell was added to England's squad for the fifth Ashes Test in January 2014.
