Dhaka, July 26 - Bangladesh's opposition parties have opted out of a team that will visit the site of the Tipaimukh dam in India's Manipur state.

While Bangladesh Nationalist Party (BNP) has conveyed that their two lawmakers would not join it, a lone member of its Islamist ally Bangladesh Jamaat-e-Islami Saturday said he had met with an accident and was unlikely to join.

The lawmaker had not sent in his travel papers in response to the government's invitation, New Age newspaper said Sunday.

'We are not going to India as part of the parliamentary delegation. It is our party decision,' the chief whip of the opposition in the parliament, Zainul Abdin Farroque, told the newspaper Saturday.

Nearly two months after India mooted the proposal for a visit by the parliamentary team, Dhaka is set to send its team Wednesday.

Led by Abdur Razzak, a former freedom fighter and minister who is the chairman of the standing committee of parliament on water resources, the team will have lawmakers, officials and an independent water resource expert.

The BNP had been insisting on five experts that it said were 'neutral'. BNP chief former prime minister Khaleda Zia has dispatched a letter to Indian Prime Minister Manmohan Singh asking him to abandon the project.
