Main opposition party CPN-UML has concluded remarks made by Prime Minister Sher Bahadur Deuba during his visit to India was an insult to the constitution-drafting Constitution Assembly and the Parliament.

'PM's remarks have not only involved external factors to country's internal matters but also insulted the historic Constituent Assembly and sovereign Parliament,' a meeting of the party's Standing Meeting under acting Chief Bamdev Gautam concluded.

In a statement, the party said raising the inappropriate dispute of acceptability of constitution by undermining the fact that the issue was resolved through voting in the parliament and dissident parties agreeing to join election would raise questions on the constitution and the faith of the prime minister.
