Singh (64) started his career from Motihari in Bihar as an ABVP Nagar Pramukh way back in 1967.
Modi had given the first inkling of Singh likely to play a big role in the BJP-led NDA government by praising him profusely at an election meeting in Motihari.
"Radha Mohan Singh is my old friend. We have worked together for a very long time," Modi had said at the meeting.
Recognising his efforts, the BJP leadership put more responsibilities on his shoulders by making him the party's Kisan Morcha Vice-President and incharge of Uttar Pradesh and Uttarkhand units.
His credentials as a man of organisation for all seasons got its final stamp from BJP chief Rajnath Singh who made the Motihari MP chairperson of the party's disciplinary action committee soon after taking over charge two years ago.
He also served as member of various committees on ministries of Railways, Communications, Petroleum and Natural Gas, Surface Transport and External Affairs during subsequent stints as MP.
An RSS Swayamsevak since childhood, he has actively worked towards welfare of the downtrodden and SC/STs.
A cricket enthusiast, the BJP MP was Vice President of the Association of Bihar Cricket.
