Peru’s President Pedro Pablo Kuczynski tendered his resignation on 21 March, the day before he was scheduled to appear before congress and fight a second attempt to impeach him in the space of three months. Ironically, the arithmetic had been looking favourable for Kuczynski surviving again, in the process delivering a severe blow to his political nemesis, Keiko Fujimori. That was until the day before Kuczynski stepped aside when he was compromised by several video recordings. Keiko has now recovered her mastery over her party, crushing a damaging internal revolt by her brother Kenji, and should reassert her dominance over the government after the first vice-president, Martín Vizcarra, takes up the reins of power.
