Next year, Mexico will become the first country in the world to begin electing all its judges by popular vote. The radical judicial reform was passed by the Senate in September, where the ruling Morena party hold a commanding majority. They argue the change will promote transparency and accountability in a justice system which has faced accusations of corruption, nepotism, and bowing to political and criminal pressure. But critics say it is a direct threat to democracy which weakens the ability of the judiciary to hold the government to account - including the Supreme Court.

On today's episode, Lucy Hockings is joined by the BBC's correspondent in Mexico, Will Grant. They examine the politics behind this shakeup, and discuss why many members of the legal community are protesting the measures.
