The legislative election in Peru was held on 11 April, the same day as the presidential election. I have not seen the final official results, but I have calculated the percentage of votes from information provided by the Electoral Commission and the seats from a newspaper report. Here are the figures:

Gana Perú (Peruvian Nationalist Party), 25.3% (47 seats, up 2)
Fuerza 2011, 23.0% (39 seats, up 26)
Perú Posible, 14.8% (19 seats, up 17)
Alianza por el Gran Cambio 14.4% (12 seats, new party)
Solidaridad Nacional, 10.2% (9 seats, down 8)
Partido Aprista Peruano, 6.4% (4 seats, down 32)

The Congressional election is a one-round vote. The presidential election is a two-ballot vote. The second round will be held on 5 June. The remaining presidential candidates represent the Gana Perú and Fuerza 2011 movements. Bearing in kind that these groups are themselves coalitions, the net result is that the next president will not be supported by a coherent majority in the legislature, though this is nothing new in Peru.
