The Pakistan Cricket Board planned to send a group of secret monitors to keep an eye on its cricketers during their May-June tour to England, in an effort to stop players from involving in any scandal, sources said on Tuesday.

Official sources told Xinhua that the PCB had almost devised a strategy to avoid any scandal or controversy during the upcoming tough tour.

"The decision came after watching the history of our team's tour to England. Whenever our team went to England, the players were dragged into some controversy by media or any other means," the sources said.

Pakistan team will start its tour to England on May 17 where it will play two One-day International matches each against Scotland and Ireland before participating in the eight-nation ICC Champions Trophy scheduled to start on June 7.

The main job of the undercover observers will watch the players' activities inside and outside the hotel and grounds.

According to the sources, the PCB has also finalized a list of rules and regulations for the tour and all the players will have to sign on a specific agreement.

Under the agreement, a strict observation will be managed over the usage of phone and Internet by the players during their official stay in England.

Players will not be allowed to move freely in public and participate in dinners or parties. But the tour management committee will make arrangements for the team's collective tours for shopping and recreations.

During Pakistani team's last tour to England in 2010, they earned a big shame for the country when three top players were found involved in a spot-fixing corruption scandal.
