Toro Rosso has agreed a three-year deal with Honda for a supply of the Japanese manufacturer's Formula 1 engines, starting next season, Motorsport.com has reported.

McLaren's desire to end its relationship with Honda kicked discussions with Toro Rosso into play to part with Renault to free up a supply of the French manufacturer's engines.

Following extensive talks, an agreement has been reached by all parties, though official confirmation is not expected until later in the Singapore Grand Prix weekend.

Sources close to the deal have confirmed to Motorsport.com that Toro Rosso has agreed a three-year deal from 2018 with Honda, taking it to the end of the current F1 engine regulations cycle at the end of 2020.
