Liam Lawson casts doubt over 'legality' of race-defining Charles Leclerc overtake

Liam Lawson has cast doubt over the legality of Charles Leclerc's late overtake on him for seventh place in the Sao Paulo Grand Prix.

On lap 69 of 71 in the wet conditions, Leclerc biffed Lawson out of the way at Turn 12 to climb the hill, with the right-front tyre making contact with Lawson's left-rear, forcing the New Zealander wide.
