Shimla, Aug 21 - A three-day Bharatiya Janata Party (BJP) meet that began on a stormy note with the expulsion of veteran leader Jaswant Singh concluded Friday, with the party admitting it needed to clearly articulate its ideology of 'cultural nationalism' to expand its base.

The meeting began Wednesday in the sylvan setting of this hill station but against the backdrop of a controversial book by former external affairs minister Jaswant Singh praising Mohammed Ali Jinnah and the advice of the party's ideological fountainhead Rashtriya Swayamsevak Sangh (RSS) to usher in a generational change in the leadership.

The first on the 'chintan bhaitak' or introspection meet's agenda was the expulsion of Jaswant Singh, who has held key portfolios of external affairs, defence and finance in BJP-led governments and spent three decades in the party since its inception, for his book 'Jinnah - India, Partition, Independence.'

But the meet glossed over discussions on a change of guard at the top, with BJP president Rajnath Singh saying octogenerian leader L.K. Advani would continue to play a major role in the party. 'Yes, he will remain the leader of the party,' he told reporters here.

Briefing reporters at the end of the meet, Rajnath Singh said: 'We will come out with a future action plan, you can call it the road ahead, on the basis of suggestions during the chintan baithak. The larger goal would be the social and geographical expansion of the party,' he added.

The plan would be presented at the national executive meeting expected to be held in September or October for its approval, he said.

The BJP chief said it was unanimously felt that to expand the party's social base, it needed better participation of youth, women, weaker sections, the poor, farmers, the Scheduled Castes and Scheduled Tribes in the party and in the states it ruled.
