The 16th National Assembly (NA) on Wednesday came into effect with the oath-taking of newly elected MNAs following the February 8 general elections. The oath to the newly elected MNAs was administered by Speaker Raja Pervaiz Ashraf. The house which was scheduled to take place at 10 in the morning, started after 11. The NA session started with a ruckus as soon as the national anthem ended with the Pakistan Tehreek-e-Insaf (PTI)-backed lawmakers, who have joined the Sunni Ittehad Council (SIC), surrounding the speaker’s dias.
