Lalji had worked closely with the jailed leader Hardik Patel who led the first round of agitation last August.
Addressing reporters here, Lalji said the Government had so far not met their demands of reservation as well as release of Hardik and other jailed conveners of the Patidar Anamat Andolan Samiti (PAAS) who are facing sedition cases.
"We gave a memorandum of demands to the Chief Minister Anandiben Patel on March 11 and gave one month's ultimatum. Till today we have not received any positive feedback. So SPG has decided to start a civil disobedience movement against the government from the next month," he said.
"We will also file a PIL demanding a stay to government recruitment till the decision on reservation is not taken. We will also demand a free and fair inquiry into the police atrocities committed on Patels during our agitation in August," said an SPG member and the lawyer Rohit Patel.
Lalji also clarified that Patels should be given reservation under EBC (Economically Backward Class) quota.
"We have asked for reservation under OBC quota earlier, but now we want it under EBC quota to avoid confrontation with OBC communities," he said.
