Rahul�s membership has been terminated by the assembly Speaker Udai Narain Singh for voting against the official candidates in the Rajya Sabha byepolls.
Known for switching his loyalties at regular intervals, Jagdish Sharma had won the Ghosi seat in 1977, 1980, 1985, 1990, 1995, 2000 and in both the elections in 2005. He entered the Bihar legislative assembly first time from Ghoshi as an MLA of Janata Party in 1977. He contested the next assembly elections in 1980 on the ticket of the BJP. His next three wins in 1985, 1990 and 1995 came as a nomine of the Congress.

In the bye-election held to the Ghoshi assembly constituency in 2009, his wife Shanti Sharma emerged victorious as an Independent.

However, in the next general assembly elections in 2010, Jagdish Sharma�s son Rahul Kumar managed to get the party ticket and won the elections.
