Fourteen opposition parties have demanded a discussion on the Pegasus issue in Parliament followed by a reply from the home minister, claiming the matter has "national security dimensions".

"It is unfortunate that the government has unleashed a misleading campaign to malign the combined opposition and blaming it for the continued disruption in Parliament," read a joint statement from the opposition.

"The responsibility for the deadlock lies squarely at the doorsteps of the government, which remains arrogant and obdurate and refuses to accept the opposition's demand for an informed debate in both the houses," statement added.
