Senior BJP leader Atal Bihari Vajpayee will participate in the party's election campaign in Maharashtra on Sunday.

Vajpayee was earlier scheduled to campaign in Maharashtra for five days beginning October 4, but the programme was cancelled due to pain in his knees.

The former prime minister will address a rally in Mumbai on the penultimate day of campaigning for the Maharashtra polls, party sources said on Thursday.

Shiv Sena chief Bal Thackeray is also likely to address the rally along with Vajpayee.
