The Congress will soon review its support extended to the Rashtriya Janata Dal ministry led by Rabri Devi in Bihar, partys state unit president Sarfaraz Ahmed said here yesterday. We will soon take up the matter whether to continue support to the minority government in the state at an appropriate level, Ahmed said. Asked to specify the reason for such a review, Ahmed said, such a situation arose following a change in the Congress leadership. A review has also become inevitable to assess our performance particularly in view of the alliance with the ruling RJD in the just-concluded Lok Sabha polls in the state, he added.
