The BJP and VHP and their parent group, the Rashtriya Swayamsevak Sangh, have asked the government to bring out a bill in Parliament to build a temple, bypassing the Supreme Court.
Ahead of Sunday's rally, police stepped up security, with organisers expecting hundreds to gather at Ramlila Maidan. Police said vehicles will be barred on Ranjeet Singh Flyover (from Guru Nanak Chowk to Barakhambha Road), JLN Marg (from Rajghat to Delhi Gate), Chaman Lal Marg near VIP gate.
The calls for a temple come ahead of Lok Sabha elections that must be held by May 2019, when Modi will seek a second term.
