<i>Reasons for U-turn </i>

Paschimbanga Chief Minister Mamata Banerjee has thrown a wrench into the signing of Teesta water-sharing treaty, claiming she has not been consulted about the final draft of the deal.
Indian Foreign Secretary Ranjan Mathai yesterday said no agreement will be signed without consultation with the West Bengal government, reports our New Delhi correspondent.
Mathai was speaking at a press conference at the external affairs ministry on the eve of Indian Prime Minister Manmohan Singh's visit to Dhaka.
He said, “The subject of water is a sensitive issue. We have been trying to arrive at an agreement on Teesta, which is acceptable to all parties.
"In our federal scheme of things, nothing is done or will be done without consultation with the state government. Any agreement that we conclude will have to be acceptable to the state government; at the same time, it would also have to be acceptable to Bangladesh."
An official of the Indian external affairs ministry said Mamata was well informed about the content of the deal as she was consulted three times before the draft was finalised.
Indian National Security Adviser Shiv Shankar Menon and Water Resources Secretary Dhrub Vijay Singh met Mamata in Kolkata last week and apprised her of the treaty and other issues including border demarcation and enclaves.
In fact, Menon consulted her twice in one week, the official added.
Sources in India said Mamata had objected to alleged difference between the quantum of Teesta water-sharing between the two countries in the first draft of the treaty and its final version.
She had agreed to 33,000 cusecs of water for Bangladesh in the first draft but was miffed when the figure in the final draft was hiked to 50,000 cusecs (a measure of flow rate and informal shorthand for cubic feet per second).
Her aide Dinesh Trivedi, who is also railways minister, had a heated argument on the issue with Finance Minister Pranab Mukherjee on Saturday.
Meanwhile in Dhaka, an official of the water resources ministry said the agreement on Feni, another common river, will not be signed if the Teesta deal falls through.
Contacted about the uncertainty over Teesta deal, a foreign ministry official said, "We are not formally informed about the developments. This is about their internal politics. We are still hopeful about the deals. In fact, we have prepared our final papers and waiting for those to be signed."
The deal on Teesta, which originates in Sikkim and flows through the northern part of West Bengal before entering Bangladesh, was a big-ticket item on the agenda of Manmohan's visit.
The Indian sources said Mamata is apprehensive of the political fall-out from the Teesta accord in the northern districts of West Bengal state, where people are already upset over her government's signing of an agreement with Gorkha outfits for an autonomous body to run Darjeeling hill areas.
She fears the Teesta deal might aggravate the drought and flood situations in six northern districts.
It is also understood that Mamata has got a wind of the possibility that her main rival the Left Front was preparing for street agitation if she gives consent to the 50,000 cusecs of water to Bangladesh.
Besides, she is aiming to make political inroads in northern parts of West Bengal, traditionally a bastion of her coalition partner Congress party, to expand Trinamool Congress' political and electoral base there.
Protecting and expanding political turf appear to be more important to Mamata than any diplomatic initiative by the federal Indian government, added the sources.
