A controversial overhaul to electoral law that critics say is aimed at boosting Giorgia Meloni’s chances of clinging on to power in elections next year has been given final approval by the Italian parliament.

Meloni, the Italian prime minister, says the new system, which introduces a fully proportional model, including bonus seats for any coalition that wins the most votes, will bring about greater political stability, while opposition parties argue that it mainly serves the interests of those in power.
