All the front-runners but Piastri finally gave up on their dry tyres and came in for intermediates on lap 28.
Once the Australian pitted, it was Norris back in the lead with Hamilton 3sec further back.
“Okay Lewis, this is our time,” said Mercedes engineer Peter ‘Bono’ Bonnington on the radio as the rain continued to hammer down.
Russell then had to retire with a water pressure issue, but Hamilton pressed on, taking chunks out of Norris sector by sector.
The fickle weather soon changed again though. With the sun bursting through the clouds and drying the track, Hamilton dived in for soft tyres on lap 39.
It proved the right call. Using the fresh Pirellis, the Mercedes driver’s undercut proved highly effective against a flailing Norris who was stuck behind traffic, who went a lap too long on intermediates.
Come the moment of reckoning, Hamilton rocketed past as Norris slithered out of the pitlane following his stop. The crowd were in raptures once more as F1’s most successful driver was back in the lead.

The McLaren man had chosen to use old soft tyres instead of new mediums, a decision that proved terminal.
His Pirellis having less life in them, Norris was unable to mount a challenge to Hamilton, and then fell back into the clutches of the charging Max Verstappen.
The Dutchman got past with four laps to go and a 3.3sec gap to Hamilton, but here the latter’s brilliance was on display once more.
The Brit had been saving his tyres while Norris struggled, and once Verstappen was past, was able to unleash the performance left in them to maintain his margin.

Hamilton remained unchallenged to the end, with the Silverstone faithful roaring him over the line as he took an incredible ninth British GP win.
“What a victory, Hamilton is back!” exclaimed Sky commentator David Croft, before emotionally-charged team radio messages were soon broadcast.
