Hardik also asked Leader of Opposition in Gujarat Assembly Shankersinh Vaghela of Congress to clarify the party's stand on the quota issue.
He penned two letters, dated May 11, one to Patel and the other to Vaghela from Lajpore jail in Surat. The letters were circulated to the media today.
Hardik urged Patel to provide all the official documents and government resolutions issued by the BJP government to implement the 10 per cent EBC quota.
According to Hardik, he along with quota body PAAS as well as entire Patel community "is still in darkness about various provisions made by government" in this additional reservation.
He claimed in his letter that he wanted to understand these provisions and convey it to the community, so that they can take a decision about the ongoing agitation.
In another letter, which was made public by his Surat- based lawyer Yashwantsinh Vala, Hardik asked Vaghela to clarify Congress' stand about 10 per cent EBC quota, as his party had demanded that government should double the quota and raise the income limit to Rs 12 lakhs.
Hardik asked Vaghela whether Congress is serious about the demand of 20 per cent EBC quota and increase in income limit.
He also hinted at supporting Congress if the party promises to double the quota when it comes to power.
