P Padmakumar, a former state Secretary of the 'Hindu Aikya Vedi', had joined CPI(M) on November 27, after snapping his four-decade-long link with the Sangh.
In the presence of CPI(M) district Secretary Anavoor Nagappan, Padmakumar had told reporters here that he had decided to join CPI(M), after being fed up with the "political violence" and "inhumane stand" of the BJP-RSS.
However, the leader announced his return to RSS fold in a meeting organised by Yuva Morcha here last evening.
"My experience and feelings while being in CPI(M) was similar to that of a nationalist caught in the midst of IS terrorists," he alleged.
He also claimed that the press release distributed by CPI(M) leaders at the press conference on November 27 did not reflect his views.
Padmakumar, while announcing his decision to join CPI(M), had said that "I was against the inhumane attitude of RSS and its politics of violence. The demonetisation of Rs 1000 and Rs 500 was the last straw and I decided to quit the outfit.
