Kalyani (WB), Jan 22 (Agencies): Social worker Dr Binayak Sen, imprisoned for life over alleged links with Maoists, may never get to see free sky again because of conspiracy of a few powerful people, Sen's mother said on Saturday.

"I fear my son will not be granted bail by the Chhattisgarh High Court on January 24 as some powerful people are a hatching conspiracy to influence the judiciary,"
84-year-old ailing Anashua Sen said here.

"I'll, however, fight for his release till the last drop of my blood and up to my last breath. If nothing positive comes out, I'll move the Supreme Court and write to the
President and the prime minister," she said.

"I'll also try to mobilise people for a strong campaign against the injustice done to Binayak," she said.

She alleged that his son has been kept in solitary confinement to create mental pressure on him. Barring his wife and daughter, none is allowed to meet him in jail, she said.

On December 24 last year, Additional Sessions Judge B P Verma in Raipur convicted 61-year-old Sen, vice-president of People's Union of Civil Liberties, for sedition and sentenced
to life imprisonment along with Naxal ideologue Narayan Sanyal and Kolkata businessman Piyush Guha for colluding with Maoists.
