Liam Lawson has kept his Silverstone Formula 1 sprint point after being let off with a warning for blocking Isack Hadjar - with Hadjar himself having urged the stewards not to give Lawson a penalty.

F1 stewards investigated Lawson post-race, after he appeared to move late trying to block Hadjar's Red Bull from passing him into Stowe late on, summoning him to discuss a potential ‘abnormal change of direction’.

Lawson argued to the stewards that he was “still at full throttle and had not yet commenced braking, and that the movement of the car was part of deceleration and preparation for the corner rather than a movement under braking”.

And Hadjar backed him, saying Lawson had left enough space and didn’t deserve a penalty.

“The driver of car 6 [Hadjar] stated that the move by car 30 [Lawson] was sharp, but also that sufficient room was left and that contact was avoided,” the stewards’ report continued.

“In his view, the incident did not merit a penalty. He also referred to the fact that the two cars were on different energy levels, which made the closing speed difficult to judge.”

The stewards accepted all those arguments and that a “stronger penalty” was not required.

But they still felt Lawson’s move “was sufficiently late and abrupt that it warranted a formal caution”, describing it as “marginally over the limit of what is acceptable when defending into a corner”.

Lawson had fended off Hadjar by 0.7 seconds on the road to claim eighth and the sprint race’s final point.
