Khurshid said he had cautioned that there would be no agreement between India and Pakistan, particularly when the state was headed for the polls. He said that Modi raising this issue should draw the attention of the Election Commission.

Sir Creek like Siachin is a long standing disputed issue between India and Pakistan.

'I think it is something to reflect on, that some good decisions you take, you are told during elections you can't take them... then somebody should take account of this (Modi) as well... Is it permissible,' Khurshid said at the sidelines of the Energy Security Conference 2012 organised jointly by the Confederation of Indian Industry (CII) and Ministry of External Affairs here on Thursday.

'If you can't raise (the cap on subsidised) gas cylinders from six to nine, can you raise such an issue of international relations? It should be taken up with the Election Commission; what are the permissible limits of issues that can be taken up during elections,' he said.

Modi had written a letter to Prime Minister Dr Manmohan Singh on Wednesday, cautioning against any possible agreement on Sir Creek — the 96-km strip of water dividing the Pakistani province of Sindh and the Kutch region of Gujarat.

In the letter Modi said that handing over Sir Creek to Pakistan 'will be a permanent threat to the fishermen of Saurashtra and Kutch and also vital defence installations and major industrial installations like refineries and ports'.

'Sir Creek is a part of our body. We cannot give away a part of our body,' he said in the letter.
The Prime Minister’s Office (PMO) has taken exception to the content of the letter and the timing of its release.
'The contents of the letter and the timing of its release to the public raise questions about the motives behind its issue,' the PMO said.

The PMO has termed Modi's letter as “mischievous” and also raised questions on the timing of the letter, written a day ahead of the first phase of polling in Gujarat and two days ahead of Pakistan Interior Minister Rehman Malik's visit.
