Prorogation of Parliament is a common practice in Sri Lanka, but it is usually done for a short period. In this case, the President is considering proroguing Parliament for two months, which would allow him to appoint a new COPE chairman and renew the sectorial oversight committees.
This would make way to remove Ranjith Bandara, who is accused of having conflict of interest issues on the Sri Lanka cricket issue.
However, proroguing Parliament is not without its risks. It could be seen as an attempt to stifle criticism of the government, and it could also lead to more protests and demonstrations. Additionally, it would give the government more time to implement unpopular policies without having to face scrutiny from Parliament.
The president will need to carefully consider these risks and benefits before making a decision. He will also need to consider the political climate in the country and the level of public support for the government.
