Mumias East MP Peter Salasya now says he will take off his hat as a lawmaker and fit in the shoes of normal Kenyans on Monday.
Salasya confirmed attendance at the planned mass action led by ODM Party leader Raila Odinga.
"On Monday I will be just a normal Kenyan. I will not be an MP and no MP should call me mhesh," Salasya tweeted.
He faulted President William Ruto's regime for ignoring concerns raised by Kenyans.
"They have failed to call President to demand enough reasons why our economy is in limbo. We expect all police officers to join our peaceful demo," he added.
Raila has called on his supporters to assemble in Nairobi on March 20 for what is billed as a dare-devil rally to reclaim his 'stolen victory'.
President William Ruto warned against chaotic protests and asked the opposition to work with the police to ensure the safety of Kenyans.
Raila's allies have lined up roadshows across the city estates on Saturday and Sunday to prepare the ground for the mega rally set to be attended by thousands of Azimio supporters.
The mobilization rallies will be led by Azimio MPs in Nairobi and MCAs as well as grassroots leaders.
Azimio's leadership has already given Members of Parliament a go-ahead to transport more supporters from rural areas for Raila's most consequential political move in recent history.
