"The government said it will reveal 136 names out of a list of 800. Why is the government being selective... in revealing the names," Congress spokesperson Abhishek Singhvi said.
The Congress also slammed the BJP-led government for "threatening" it over the list.
"Threatening Congress over black money will not help. The people want the black money to be brought back, have they got even Rs.500 back?".
Another party spokesperson Ajay Maken said Congress "will not succumb to blackmailing".
"We want to know the entire list. Do not blackmail and threaten us. The Congress party is not going to succumb to any blackmailing," Maken said.
Maken said the people of the country do not just want to know the names. "They are waiting to know how the money will come back to India."
Finance Minister Arun Jaitley Tuesday said Congress will be embarrassed once the names of people holding illicit foreign accounts are made public.
