Shah last played for England in the Champions Trophy in October 2009
Middlesex have revealed that they are not planning to renew England batsman Owais Shah's contract for next season.
"The team needs freshening up if the fortunes of the young side are to improve," said Middlesex managing director of cricket Angus Fraser.
"Owais has given total commitment to Middlesex in 2010 but I feel a change will be good for him and the club."
Middlesex have also ended speculation over Eoin Morgan's future by persuading him to pen a new two-year contract.
Morgan, one of England's centrally contracted players, had been linked with a move to Warwickshire earlier this summer, while Surrey and Sussex were also reportedly keen on landing the Irishman's signature.
"I am delighted to continue my career at Middlesex," said Dublin-born Morgan, 24, who first joined the side as a 16-year-old.
"The club have played a major role in me getting to where I am now and the future looks very healthy. I am looking forward to playing my part when my England commitments allow."
Shah, 31, has made one Championship ton this summer, hitting 633 runs in 12 games at an average of 33.31.
He has hit 267 runs in eight innings in the CB40, as well as plundering 421 in the T20.
But his place came under threat following this week's signing for 2011 of Derbyshire's Australian opener Chris Rogers.
Pakistan-born, Isleworth-educated Shah, who made his Middlesex debut in 1995, has scored more than 20,000 runs in all forms of the game in his 16 seasons at Lords.

He has also made six Test appearances for England - hitting 269 runs, including a best of 88 on his debut against India at Mumbai in March 2006 - and 71 one-day internationals and 17 Twenty20s.
In 199 first-class matches, he has hit 37 hundreds but his career highlight at county level was winning the Twenty20 Cup with Middlesex at The Rose Bowl in 2008 when he blasted 75 in the final against Kent.
Fraser added: "Saying goodbye to a player who has represented your club with distinction for such a long period of time is very hard.
"I have always been extremely fond of Owais, who began to emerge as a player of exceptional talent as my playing career reached its conclusion.
"It was a delight to watch him go on to play and perform well for England.
"Owais will play in Middlesex's remaining fixtures this season, giving the supporters a final chance to show their appreciation for one of the club's leading modern players.
"It goes without saying that I wish him well wherever he goes and I am sure he will score plenty of runs there."
