Nasir Jamshed has pleaded guilty to conspiring to bribe fellow cricketers in the Pakistan Super League.
The former Pakistan batsman had earlier denied being part of the plan but changed his plea amidst his trial at Manchester Crown Court.
Jamshed, 30, could possibly face imprisonment for his actions with the sentence set to be announced in February 2020.
He and two other men, Yousef Anwar and Mohammed Ijaz, have admitted to offering financial inducements to cricketers in the PSL with the intention of fixing matches.
Anwar and Ijaz had created a system that would include charging £30,000 per fix with half of the amount going to the player while Jamshed was the go-between for them as he tried to encourage other cricketers.
These findings came to light as a result of an undercover operation where a police officer pretended to be a member of an illegal betting syndicate.
The prosecutors explained how the policeman's efforts helped them identify an attempted fix in the 2016 edition of the Bangladesh Premier League and an actual fix conducted in the PSL in 2017.
Jamshed was the targeted individual in the BPL case while he acted as the intermediary during the spot-fix in the PSL.
In both instances, an opening batsman was supposed to play out two dot deliveries as part of the agreement with the bookies.
The PSL fixture involving Islamabad United and Peshawar Zalmi in Dubai on February 9 that year saw Sharjeel Khan follow the plan. The hard-hitting opener was later banned by the Pakistan Cricket Board for five years, with half of his sentence suspended.
Meanwhile, Jamshed was slapped with a ten-year ban in August 2018 after an investigation by the PCB's anti-corruption unit.
Ian McConnell, Senior Investigating Officer of Britain's National Crime Agency (NCA), said: "These men abused their privileged access to professional, international cricket to corrupt games, eroding public confidence for their own financial gain.
"Tackling corruption and bribery in its various forms is a priority for the National Crime Agency.
"We will vigorously pursue those involved and target their illicit profits which are so often used to fund further criminality."
Jamshed made his international debut in January 2008 and last turned out for Pakistan in the 2015 ICC World Cup.
