The England and Wales Cricket Board is on the lookout for a new sponsor after Brit Insurance confirmed it would not be renewing its contract.
The company has been the England team sponsor since 2010 with its logo featuring on all playing and training apparel worn by the England men's and women's cricket teams and the England Lions and England Disability teams.
Brit informed the ECB of the decision not to renew its contract early in order that a suitable successor for the prestigious partnership could be sought and to enable an appropriate hand-over period.
"The ECB thanks Brit for what has been an important and successful partnership for both parties," said ECB commercial director John Perera.
"Brit has benefited from significant exposure as both the men's and women's teams have achieved extraordinary levels of success since the partnership began in 2010.
"Our search for a new sponsor will begin immediately and we anticipate significant interest from potential partners who wish to be associated with the England cricket teams."
During Brit's sponsorship the England cricket team won the ICC World T20 (2010), regained the Ashes in Australia (2011), climbed to world No 1 in the ICC ODI rankings and are currently ranked second in the Test rankings (2012).
England Women are still top of the ODI rankings, and are reigning ODI world champions.
