The demonstrators, who came from Uttar Pradesh, Rajasthan, Madhya Pradesh and Karnataka under the banner of Pension Parishad gathered at PM's 7, Race Course Road residence at around 2:30 pm and staged a demonstration.
The protesters claimed they had to come to the PM's residence as even after several assurances by Rural Development Minister Jairam Ramesh and other leaders, nothing has been done so far to restructure the existing pension scheme despite rising inflation and poverty.
The elderly have been protesting at the Jantar Mantar here since November 27 demanding the government immediately introduce universal and non-contributory old age pension system with a minimum dignified monthly pension amount.
