Finance Minister Pranab Mukherjee always tries to maintain balance between various political forces. While he fully supports Trinamool Congress chief and Railway Minister Mamata Banerjee’s rise to power in West Bengal, he also maintains cordial relations with the ruling Left Front government. Last week, Mukherjee flew down to Kolkata to take part in a foundation stone-laying ceremony of the railway ministry. But he quickly planned another such ceremony with West Bengal Chief Minister Buddhadeb Bhattacharjee on Monday. The second one was for setting up a campus of the Aligarh Muslim University (AMU). But the plan got cancelled at the last moment as Mukherjee was informed that the AMU administration had not yet received all the requisite permissions.
