Bhopal, Nov 1(PTI): Prime Minister Narendra Modi will launch BJP's membership drive on Saturday with a target to increase its strength.

"As per the BJP's constitution, the party renews the membership every two years. Tomorrow (Saturday), Narendra bhai will launch party's new membership drive with an aim to increase its strength by four times than the present one," party president Amit Shah said on Friday while addressing the Karyakarta Sankalp Adhiveshan in Bhopal ahead of local bodies elections in Madhya Pradesh.

"A toll-free number will also be launched and people would be asked to give a missed call on it. After that they will get their membership number and other details through SMS," he said.

In states like Madhya Pradesh, Rajasthan, Gujarat, Goa and others where the party is strong, the BJP will have to increase its membership by four times and work further towards cementing it permanently, he said.

Madhya Pradesh has to raise its membership to two crore this time, as per the target, he said. In states where the party is not that strong, it has to ensure that the membership drive reaches from cities to towns, village and to booth level, the BJP leader said.

The frontal organisations too have been given the task of registering full-time party members. BJP is the only party in the country which follows internal democracy in totality by holding elections every two years, Shah claimed.
