Former Sussex cricketers Lou Vincent and Naveed Arif have been charged with alleged match-fixing under the England and Wales Cricket Board's Anti-Corruption Code.
Ex-New Zealand cricketer Vincent has been charged with 14 offences in relation to county matches, which include a Twenty20 match between Sussex and Lancashire as well as a 40-over game between Sussex and Kent in August 2011.
Arif has been hit with six alleged offences, which are in relation to the same over-40 game from three years ago for which Vincent is facing charges.
Head of ECB's Anti-Corruption unit Chris Watts said: "This has been an extremely complex and lengthy investigation co-ordinated across many jurisdictions around the world. This matter is now the subject of formal legal proceedings and we will therefore make no further comment other than to reiterate our determination to bring to account the very small minority who seek to corrupt cricket."
ECB chief executive David Collier added: "The ECB's ACCESS unit has worked tirelessly in conjunction with the ICC's ACSU to bring about these charges, which once again demonstrates the ECB's zero-tolerance approach to corruption in our great game."
Both players have been provisionally suspended from all cricketing activities.
