There is a new PM is Peru. The previous PM, José Antonio Chang Escobedo, resigned for personal reasons and was replaced by the Minister of Justice, Rosario del Pilar Fernández Figueroa. She is an independent and continues to hold the position of Minister of Justice.
Should you wish to see it there is footage of her swearing-in ceremony here.
We would expect it of a president-parliamentary system, but it is worth noting that PM Chang was appointed in September 2010 and that, prior to his appointment, the average tenure of a Peruvian PM was just 11 months. PM Chang has just reduced that figure by a small amount.
