Thiruvananthapuram: Uproarious scenes marked the opening day of the budget session of the Kerala Assembly on Wednesday after the Opposition UDF tried to block Governor Arif Mohammed Khan in the House on his way to the Speaker's dais to deliver the policy address. Shouting slogans and holding placards reading "Recall Governor' and 'No to CAA, NRC', the UDF legislators gathered in the well of the House, blocking the path of Mr.Khan who was escorted by Chief Minister Pinarayi Vijayan and Speaker P.Sreeramakrishnan. Unfazed by the protest, the Governor greeted the members with folded hands and remained standing as the Speaker and Law Minister A.K.Balan tried to persuade the UDF members to provide a safe corridor but to no avail. With the protestors showing no signs of retreat, the Speaker requisitioned the watch and ward to clear the path. The security personnel had to forcibly drag the protestors out of the way and clear a passage for the Governor to the Speaker's dais. After the national anthem, the Governor began by inaugurating the e- Assembly project and went on to deliver the policy address, even as the UDF members staged a walk out, boycotting the day's proceedings. They later held a rally to the gate of the Assembly complex and staged a sit- in. Earlier, before the Governor's address, the Opposition legislators spread banners against CAA and NRC across their desks. The UDF parliamentary party meeting held before the day's session had decided to block the Governor inside the House as a means of protest.
