Observers say that government at the Centre will try to create problems for Mamata in running her government in West Bengal.
"Of course, UPA leaders won't be silent spectators to every moves of Mamata. They will definitely reply back to her. A tug-of-war, or call it a cold war between Mamata and UPA government is sure to commence soon," said a political analyst.
The "cold war" seems to have already started. In its first direct attack on Mamata, the UPA government has decided to shift the International Investment Meet from Kolkata in West Bengal to Agra in Uttar Pradesh, informed sources.
The summit was intended to bring large-scale investments in the country.
Sources add that Commerce Minister Anand Sharma has already given his nod, confirming Agra as the new venue for the summit. Sharma has written a letter to Uttar Pradesh Chief Minister Akhilesh Yadav in this regard.
However, Congress leaders deny any "cold war" theory between Mamata and UPA government.
Many are saying that the venue of the summit has been shifted as West Bengal government is not providing any support to conduct the international event.
Recently, Mamata withdrew her support from UPA government over the diesel price hike, LPG cap and FDI in retail.
