The three players have been charged under the ICC’s Anti-Corruption Code following the News of the World investigation into spot-fixing that has rocked the cricketing world.
Lawyers have confirmed their clients will leave England after being questioned by police last week.
Addleshaw Goddard said in a statement: “The Metropolitan Police has been notified that Mohammad Amir, Mohammad Asif and Salman Butt will return to Pakistan later this morning.
“The players are looking forward to being reunited with their families. They remain available to co-operate fully with the police investigation and have each given undertakings to return to the UK if required to do so.”
Businessman Mazhar Majeed is accused of accepting £150,000 to arrange for Butt, Asif and Amir to deliberately bowl no-balls during the fourth Test at Lord’s.
All three deny any wrongdoing.
Wahab Riaz is also being set to be questioned by police on Tuesday in relation to the allegations of corruption.
