Prime minister Ranil Wickremesinghe on November 19 submitted to the CC the reports of six subcommittees tasked with making recommendations for a new constitution.
Dr. Wickramaratne said the recommendations included an expansion of the civil and political rights, right to freedom against enforced disappearances and the right to personal safety.
