Red Bull have requested a review of the penalty given to Mercedes' Lewis Hamilton after his first-lap collision with Max Verstappen at the British Grand Prix.

Hamilton was ruled to have been "predominantly to blame" for the crash, which resulted in Red Bull driver Verstappen being taken to hospital.

The Briton was given a 10-second penalty but recovered to win the race.

Both teams have been summoned to appear via video link on Thursday.

Red Bull want the penalty increased but will need to present new evidence which was not available at the time of the original inquiry for seven-time world champion Hamilton to be sanctioned further.

The stewards will then consider Red Bull's findings and decide if it constitutes new evidence and whether to proceed with a review.

Verstappen accused Hamilton of being "disrespectful" and "unsportsmanlike" after the crash, with the 23-year-old Dutchman being taken to hospital for precautionary checks after suffering an impact of 51G.

Red Bull team principal Christian Horner said the incident had cost them at least $1.8m (£1.3m), a figure which is more than one percent of the team's total budget this season.

Meanwhile, Mercedes chief technical officer James Allison said Hamilton's penalty was "harsh".

Briton Hamilton, 36, passed Ferrari's Charles Leclerc with two laps to go for victory and combined with Verstappen's retirement, he cut his rival's championship lead from 32 points before the race to just eight.
