While preparations for the upcoming state polls and the 2019 general election will be part of the agenda, the meeting's focus will be on arming the delegates with an array of arguments against the critics of the government's economic policy.
"The BJP has completed 3.5 years. It was felt important to reflect upon what all has been achieved and what more needs to be done. Some policies have worked, some will show returns later but the mood of the nation and the party should remain upbeat," said BJP Delhi Chief Manoj Tiwari to NDTV, who is organising the event.

BJP officials met in Delhi to discuss the agenda for its National Executive.
"I will host the evening. Deendayal was very fond of songs which evoke nationalism, so as a tribute, regional songs from different states will be performed with a common theme - India," Mr Tiwari had said.
NDTV has learnt that the need for an open convention was felt after the Rashtriya Swayamsevak Sangh (RSS), the party's ideological parent, alerted the BJP about signs of a shift in public mood over the government's performance. Some of Sangh's economic fronts have even announced a protest in November to flag some of the government's failures.
Taking a cue, Prime Minister Narendra Modi's concluding address, later today, is expected to be key and the high-point of the convention. He is likely to provide the broad guidelines how the party can revitalise its connect with the people.
