The red shirts will Saturday confine their activities within the rally site at Phan Fa Bridge and decide to cancel an earlier plan to march around the capital, Metropolitan Police Region 1 commander Maj General Wichai Sangprapai said on Friday.
"Traffic woes will not happen as feared because the red shirts have decided to stay in at their rally site," he said.
Wichai was speaking after a meeting with rally organisers.
He said in regard to the IPU Assembly, the red shirts have pledged to stay away from the meeting venue at Ratchaprasong.
In lieu of rallying, the red shirts have sought and received the police permission for sending a team of three representatives to lodge a protest note with the IPU, voicing their protests against the Thai government, he said.
