The Bharatiya Janata Party and the Sangh Parivar top brass will begin a three-day informal meeting from Thursday in New Delhi to prepare for the upcoming assembly elections in Uttar Pradesh, Rajasthan, New Delhi and Chattisgarh.

Prime Minister Atal Bihari Vajpayee, Deputy Prime Minister Lal Kishenchand Advani and other top leaders of the party and the Sangh Parivar will attend the meeting to discuss a wide range of subjects like the political situation in the country, economic policies of the government and other issues, party sources said.

The exercise is a part of the BJP's efforts to have regular interaction with nationalist organisations like the Vishwa Hindu Parishad, Rashtriya Swayamsevak Sangh and Swadeshi Jagaran Manch.

BJP president M Venkaiah Naidu and general secretaries Sanjay Joshi, Pramod Mahajan, Mukhtar Abbas Naqvi and Rajnath Singh will also attend the meeting.

Others who are expected to attend include K S Sudershan and Ram Madhav from the RSS, VHP leader Ashok Singhal and SJM leader S Gurumurthy, sources said.

"This interaction will enable the parivar and the party to have a better understanding of each other's position vis-a-vis economic policies and political issues," party sources said.

The recent exchange between Vajpayee and his Pakistani counterpart Mir Zafarullah Khan Jamali is also expected to figure in the meeting to enable the party leadership to gauge the mood of the Parivar on Indo-Pakistan ties, they said.

The party had taken the stand that there was no question of talks with Pakistan till it stopped aiding and abetting cross-border terrorism, a line the Parivar is following.

Naidu had, at a recent meeting of organisational secretaries, said there was nothing wrong in talking to nationalist organisations like those belonging to the Parivar.
