New Age newspaper said opposition chief and two-term prime minister Khaleda Zia was expected to 'disclose' some data that the party had collected.

Invited to join a team of parliamentarians and water resource experts to visit India on July 29 in response to an invitation from New Delhi, the BNP has been withholding nomination of two members.

Anwar said the party would not join the team unless 'neutral' experts are included.

'The (Bangladesh) government is much interested in sending a parliamentary group and the BNP will not join such a group unless experts are included.

'Khaleda June 29 sent a letter to Sheikh Hasina naming a six-member BNP delegation, which included four experts, for a visit to the dam site in Manipur,' he said.

She had also sent a letter to the Indian prime minister asking him to desist from constructing the dam.
