New Delhi, Aug. 16 :    New Delhi, Aug. 16:  The Rashtriya Swayamsevak Sangh (RSS) found itself in strange company and an unlikely controversy today when doubts were raised in the Lok Sabha over the allegiance of the Sangh and the CPM to the national flag. The Opposition and the National Democratic Alliance members clashed in the House after Prakash Ambedkar alleged that the RSS had no respect for the Tricolour and it never hoisted the flag on its headquarters at Nagpur. The CPM, too, was pitchforked into the row as Sudip Bandopadhyay of the Trinamul Congress alleged that the Red headquarters on Calcutta's Alimuddin Street never hoisted the national flag. Parliamentary affairs minister Pramod Mahajan denied the charge against the RSS. 'I am associated with the RSS since my childhood and I would say that all RSS offices hoisted the national flag,' he said. Mahajan urged the Opposition not to reap political mileage by making such charges. The minister offered to take Bharipa Bahujan Mahasangh member Prakash Ambedkar to the RSS headquarters on January 26 next year and allow him to unfurl the Tricolour. Raising the issue during Zero Hour, Ambedkar said an all-party meeting in 1998 at Nagpur had decided to send representatives to the RSS headquarters for hoisting the Tricolour, if the organisation on its own failed to do so. Last year, Ambedkar said, when the workers of different political parties went there to raise the flag, they were lathicharged and chased. He added that this year too, the RSS resisted attempts to unfurl the tricolour on its building. Mahajan said any individual or organisation could hoist national flags on their houses or buildings on national days, but he did not see all MPs and politicians flying national flags atop their houses on these occasions. 'Does that mean that they are all unpatriotic?' Mahajan asked.
