"Modi was chief minister in 2004 when this issue was discussed. He remained silent on Sir Creek for the last eight years and has raised the issue now ahead of the second phase of polling in 95 assembly seats, falling under the Kutch, north Gujarat and central Gujarat, due on Dec 17," he said.
The strip of water that is disputed between India and Pakistan falls in the marshlands of the Rann of Kutch.
The issue was raised by Modi, who on Wednesday shot off a letter as a "common man" to Prime Minister Manmohan Singh, demanding that the disputed Sir Creek should not be handed over to the neighbouring country. The PMO had strongly rebutted the charge by saying the allegations were "baseless" and "mischievous".
Addressing an election rally here last Thursday, Modi had clarified that he raised the issue keeping in mind the scheduled arrival of Pakistani interior minister Rehman Malik in the country on December 14 when both the countries are likely to reach an agreement.
"Today is 15th December and no such agreement has taken place on the issue between the two countries, which makes it clear that it was imaginary conspiracy of Modi's mind...He is trying to mislead people of the country including 6 crore people of Gujarat", Tiwari alleged.
