An orator par excellence and known for taking bold initiatives, notable being the attempt to bridge differences in Indo-Pak relations, Vajpayee, who is lauded as a statesman politician, went far beyond his BJP's nationalist political agenda.
It was Vajpayee's sway that brought in 1998 new allies to BJP, once considered a virtual untouchable in view of its rightist leanings, especially after demolition of Babri Masjid in 1992.
Undeterred by party hawks who accused him of embarking on a misdirected visit to Pakistan in 1999, Vajpayee, who is India's longest serving prime minister outside Congress party, rode triumphantly into Lahore aboard a bus, on an initiative that was pursued by his successor Manmohan Singh.
Vajpayee's diplomatic breakthrough was hailed as the dawn of a new era in Indo-Pak relations. But it was another story that Pakistan army undertook a covert operation to send its troops into Kargil that led to a limited conflict that Pakistan lost.
The lack of a stable majority ended his second stint in power from 1998 after 13 months. His government collapsed after AIADMK supremo J Jayalalithaa withdrew her support from the coalition. He was reelected in 1999 at the head of a more stable coalition that lasted its full term.
