Daniel Kvyat and Marcus Ericsson have both picked up three-place grid penalties for next month's Canadian Grand Prix following their antics in Monaco.

Both drivers were adjudged to have caused accidents in their haste to pass rivals in what proved to be a frenetic Monaco race, in Ericsson's case taking out his own Sauber team-mate, Felipe Nasr, while battling over 15th place in the latter stages.

The Swede had been asking Sauber to make Nasr move over but the Brazilian was unwilling to heed the request, prompting Ericsson to ask whether his team-mate's radio was broken. Clearly frustrated, he attempted to make matters into his own hands, forcing himself inside Nasr at Rascasse but a lot more clumsily than the late Jules Bianchi had done on his way to Marussia's historic ninth place a couple of years ago. With Nasr still unwilling to concede the position, a collision was inevitable, with both cars eventually retiring to the pits as a result of the damage they sustained.

Adjudged by the stewards to have caused the collision, Ericsson picked up the three-place penalty for Montreal, in addition to having two points added to his licence.

Kvyat also added to his penalty points tally - taking his twelve-month running total to seven - after attempting to muscle his way by the remaining Renault of Kevin Magnussen. An initial nudge at the entry to the Swimming Pool failed to dislodge the Dane, so Kvyat had another go at Rascasse, putting both cars into the barriers. Magnussen was able to resume the race, albeit briefly, but Kvyat was out on the spot, adding another accident to a litany of mishaps that saw him 'demoted' back to Toro Rosso after the Russian Grand Prix.

The stewards' verdict explained that Kvyat, 'with two small collisions - left front (car #26)/rear right (car #20), effectively created an overtaking space which, in reality, would not have been there if the collision had not occurred'. It was a poor end to a race that had already begun badly for the Russian, who lost laps to the field when his STR11 refused to disengage constant speed mode behind the safety car.

Kvyat and Ericsson were just two of a number of drivers required to spend time with the stewards after the 78-lap race, which began behind the safety car due to the heavy rain which plagued the Principality all morning. While both Pascal Wehrlein and Valtteri Bottas picked up time penalties to be added to their elapsed race time - in the German's case on two separate occasions, which added four points to what had been a clean licence - Lewis Hamilton and Kimi Raikkonen both escaped punishment after being cited for misdemeanours.

Bottas dropped to twelfth in the final result after his penalty for causing an accident, while Wehrlein came home 14th after separate incidences of ignoring blue flags and failing to keep sufficient speed under the virtual safety car. Raikkonen retired from the race in its early stages, but was reported for driving his damaged Ferrari, complete with trailing front wing, into the tunnel before parking up at the chicane. Hamilton, meanwhile, went on to win the race having been found not guilty of failing to leave enough room for Daniel Ricciardo to insert his Red Bull during their hectic battle for victory.
