Former England all-rounder Jamie Dalrymple has rejoined to Middlesex for a second spell.
Dalrymple, 30, resigned from Glamorgan during the winter after losing the captaincy to Alviro Petersen as part of a wide-ranging overhaul of the county's leadership, which also saw coach Matthew Maynard depart.
He had been in Cardiff for the previous three years - two as skipper - after starting his career at Middlesex, where he won 27 ODI caps from 2006-2007.
The Oxford University graduate plans to join up with the Middlesex squad in mid-May but will not be considered for first-team selection until the start of the Friends Life t20 campaign at the start of June.
"I am delighted to have been able to rejoin the club I played with for so long and am looking forward to joining the squad and being a part of Middlesex CCC as it moves forward," Dalrymple told the county's official website.
"I will be watching the early season closely and wish the team every success whilst trying to get up to speed as soon as possible."
Middlesex managing director of cricket Angus Fraser believes Dalrymple's experience will be a valauble asset.
"Jamie is a fine cricketer and he will strengthen our squad," said Fraser. "He played for England at the 2007 World Cup.
"Along with his cricketing skills he is a natural leader who brings experience and know-how, qualities we have been short of in recent times.
"Jamie's departure from Glamorgan occupied most of his winter and it is only recently that he has been able to focus fully on cricket.
"At a pinch we could have rushed Jamie's return so that he was available for the start of the season, but I did not think this was right.
"I believe the Middlesex CCC players who have trained hard this winter deserve the first opportunity to stake a claim for first team selection.
"Depriving them of this opportunity at the start of the season would have had a de-motivating effect on the squad.
"The departure of Owais Shah has left us with one fewer experienced, destructive match-winning middle order batsmen in limited over cricket, and we believe Jamie can fulfil that role.
"He bowls good off-spin and is a magnificent fielder. I believe the arrival of Jamie gives our squad an excellent balance of experience and youth."
Dalrymple's first appearance could come in Middlesex's FLt20 opener, away to his former employers Glamorgan on June 3.
