Perez handed eight-place grid penalty

Sergio Perez has been handed a combined eight-place grid penalty for two incidents involving yellow flag infringements during the qualifiers for Sunday's Singapore Grand Prix.

Perez raised eyebrows after he set his fastest time during Q2. He was first handed a five-place penalty for speeding under double yellow flags for Romain Grosjean, and then another three-places for overtaking Sauber driver Esteban Gutierrez while the flags were still being waved.

The Mexican, who advanced into Q3, was convinced that Force India had enough data to show that he lifted at the correct moments, but the FIA saw otherwise.

"The driver of car 11 failed to reduce his speed significantly and be prepared to change direction or stop as required under Art2.4.5.1(b) when double yellow flags were being waved at both Turns 9 and 10," a statement from the race stewards read.

"The Stewards took into consideration the fact that the driver had two corners in which to slow down significantly and failed to do so and both of which were blind corners (including one where the accident had taken place and where the damaged car was still in the barriers) and where the driver would not have known if the track had a hazard wholly or partly blocking the track and/or marshals working on or beside the track."

The former McLaren driver will start the Grand Prix in P18.
