On the 133rd day of their relay hunger strike at Jantar Mantar here, the veterans said that the announcement made by Defence Minister Manohar Parrikar on September 5 regarding the implementation of OROP had "seven serious shortcomings".
If implemented without the removal of the shortcomings, it will kill the definition of OROP, the letter claimed.
The letter further accused Parrikar of "changing the goalpost" every now and then.
The protesting veterans asked the Prime Minister to issue notification to implement OROP scheme at the earliest.
