Decency in language should be maintained while criticising the Prime Minister, who holds the highest office in the Government, RSS Joint General Secretary Dattatraya Hosbale told reporters here.
Key aides of anti-graft crusader Anna Hazare have levelled corruption charges against Singh and some of his Ministers. The charges against the PM related to allotment of coal blocks when he was in-charge of the Coal Ministry.
Hosbale ridiculed Hazare for distancing himself from the Sangh, saying the veteran social activist had addressed its volunteers in the past.
Nagpur-based RSS had also organised programmes in Ralegan Siddhi, Hazare's native village in Ahmednagar district, he added.
