Reasons put forth for this bill include the assertion that the spirit of May 1st has become perverted, and that the Left has done nothing to avoid the holiday being taken over by extremists and hate-mongers.

Opposition parties are squarely against this reform and, having lost the parliamentary vote, are likely to try to force a referendum on the issue.
