As part of his tour to states where BJP needs to strengthen its position, party chief Amit Shah will spend two days in Tripura. The BJP national president landed in the state capital Agartala this morning. Despite Chief Minister Manik Sarkar's clean image, anti-incumbency has struck Tripura, where the Left government has been in power for five consecutive terms. With elections in the state due early next year, the party's national executive of the party has now marked Tripura as one of the key focus areas. The BJP's "Look-East policy" has already resulted in a takeover of three of the seven north-eastern states - Assam, Arunachal Pradesh and Manipur - dislodging the Congress.
