The Bharatiya Janata Party's 'Lalkar rally' is expected to be a show of strength for the party.
The M.A. Stadium can house 40,000 people but organisers say Jammu will see one of the biggest political gatherings Sunday.
"We are expecting lakhs of supporters to attend the rally," BJP legislator Ashok Khajuria told IANS. "We have been making arrangements for more than a month. It will be a historic rally."
