Senior Bharatiya Janata Party leader and former Rajasthan governor Madan Lal Khurana on Saturday demanded party president Lal Kishenchand Advani's resignation as party chief and leader of the opposition in Lok Sabha.

Khurana, a party strongman in Delhi till a few years ago, has sent a letter to Advani containing his demand.

The Rashtriya Swayamsevak Sangh and its satellite organisations have been up against Advani ever since he praised Jinnah during a recent visit to Pakistan.
