An all-party meeting has been convened by Speaker Somnath Chatterjee on Tuesday to decide on the alleged involvement of some MPs in the human trafficking case.
"This unfortunate incident puts all Parliamentarians in bad light. We have to take decisions fast to re-assert that Parliament is firm on issues which concern the conduct of MPs, as we have taken in other instances like the cash-for-query scam", CPI(M) leader Mohd Salim told reporters here.
He said the case had brought "disrepute to the institution of Parliament", not only within the country but abroad too because the concerned MPs were using their official passports to take people out of the country.
"It is not merely a criminal case, but a case involving our cultural and political ethics", Salim said.
The CPI(M) leader also hit out at the BJP for trying to "dilute" such issues by saying there were other MPs against whom criminal cases were pending.
"We cannot turn a blind eye when Parliamentary privileges and opportunities are misused by MPs. People get these privileges only after being elected to the House. We hope all parties will come together like in the case of the cash-for-query scam in which MPs' privileges were misused".
Condemning the frequent disruption of proceedings, Salim said issues reflecting "conflicting interests" were being raised regularly, instead of common issues affecting the people.
Several crucial bills, like on women's quota and social security for unorganised workers, had not even been listed for consideration, he said.
