The England and Wales Cricket board have announced a record sponsorship deal with Investec.
The international bankers have signed a ten-year deal to sponsor Test cricket in England.
"This is excellent news and a further boost for our five-day game following the England's team achievement in becoming the world's number one Test side," said ECB chief executive David Collier.
The partnership will start with the three-match series against the West Indies over May and June next summer.
