Mr Odinga said he and President Kenyatta would not force people to support the idea, saying that democracy allows for its opposition.
President Uhuru Kenyatta and Mr Odinga launched the BBI signature collection drive last week, in an event that also saw a digital platform set up for the initiative.
Orange Democratic Movement (ODM) party leader Raila Odinga is confident that the ongoing push to change the constitution will garner the requisite one million signatures. He said an overwhelming number of Kenyans have come out in support of the Building Bridges Initiative (BBI) report.
“I want to thank Kenyans who have willingly come out in large numbers to sign for the BBI. From the reports that I receive from all corners of the country, we are confident of getting more than the one million signatures that are required,” said Mr Odinga.
