He said till all matters related to the National Register of Citizens (NRC) are disposed, people and families should not be separated and the matters be kept in abeyance.
The NRC issue is of international importance as it affects relation with neighbouring countries, including Bangladesh. It also has inter and intra state repercussions, Sharma said.
"Questions have been asked over the methodology being followed in finalising the NRC. It raises question marks on the credibility of the process," he said.
He also urged the government to remove shortcomings in the entire process and that all issues be settled as per the 1985 Assam Accord signed in the presence former prime minister Rajiv Gandhi.
The problems should be sorted out in the ambit of the Assam Accord of 1985, the Congress leader said.
The draft NRC was published today with the names of about 4 million residents of Assam not being included.
