New Delhi is likely to experience a huge traffic jam on Wednesday, as the Bharatiya Janata Party holds a rally to protest against price rise.
BJP sources said they expected over 5,00,000 activists to take part in the rally.
Former deputy prime minister and senior BJP leader L K Advani, party president Nitin Gadkari, leader of opposition in the Lok Sabha Sushma Swaraj, Rajya Sabha leader of opposition Arun Jaitley and former party president Rajnath Singh are expected to address the rally.
Earlier in the day, the BJP slammed the government for its "failure" to control inflation and walked out of the Lok Sabha protesting spiralling prices of essential commodities.
Swaraj led the protest soon after the House met for the day, saying price rise was due to the "weak" policies of the government and not because of any natural calamity.
Referring to the BJP rally against price rise, Swaraj said lakhs of people from far-flung areas of the country had come to Delhi to "shake up and wake up the government from its slumber".
The government has been mired in scams and scandals and had no time to control skyrocketing prices, she said leading the walkout by Advani, Deputy leader of the BJP in Lok Sabha Gopinath Munde and other party members.
The rally is being seen as Gadkari's first show of strength as the party president.
BJP chief ministers -- Narendra Modi, Shivraj Singh Chauhan, Prem Kumar Dhumal, Dr Raman Singh, Ramesh Pokhriyal are also expected to address the rally.
The rally will begin at the Ram Leela ground and will culminate at Jantar Mantar.
