BJP today invited Gujarat Chief Minister Narendra Modi to campaign for Bihar assembly polls. BJP General Secretary and in-charge of the party for Bihar, Ananth Kumar while addressing a meeting of the party's Gujarat Executive in Ahmedabad extended the invitation to Mr.Modi. JDU leader Shivanand Tiwari refused to comment on the development.<br/><br/>Mr.Modi and other senior leaders including Mr.Arun Jaitley were also present in the meeting. Differences between the JDU and BJP who are running a coalition government in Bihar came to fore last month on a coule of advertisement published in local dailies showing Modi and Nitish Kumar holding their hands together. Nitish Kumar also returned 5 crore rupees being the unspent money of the aid given by the Gujarat government in 2008 to Bihar at the time of Kosi floods.<br/><br/> The joint campaign by Nitish Kumar and Deputy Chief Minister Sushil Modi was also called off in the wake of the spat but later it was decided to be resumed. Nitish Kumar had also cancelled a dinner for its top leadership in Patna when they were there for a meeting of the National Executive.
