The party has asked its 281 Lok Sabha members, 56 Rajya Sabha members, close to 1,400 MLAs, its MLCs and members of its core group of states to attend the event to be addressed by Prime Minister Narendra Modi and party president Amit Shah.
The national executive meeting is generally attended by less than 200 members, including permanent and special invitees.
The party leadership has decided to make it a mega exercise, described as extended national executive by party sources, with an apparent aim of directly communicating its stand on a range of issues and vision for the coming years to its elected representatives and top leadership across the country.
On the eve of the extended national executive meeting, the party's office-bearers will meet of September 24 to hold discussion over the issues, including resolutions, to be taken up the next day, the sources said.
