Lewis Hamilton's victory in the Italian Grand Prix will stand after stewards decided to take no further action regarding Mercedes' tyre pressures.

A technical delegate report issued by the FIA, the sport's governing body, had claimed Hamilton's left-hand side rear tyre was "0.3 psi below the minimum tyre starting pressure".

However, Formula One officials announced that the original result would stand after a post-race inspection.

The victory means Hamilton is closing in on a third world title as he leads the championship by 53 points from team-mate Nico Rosberg.

The 30-year-old held off the challenge from Ferrari's Sebastian Vettel on the run down to turn one and from there he never looked back.

Vettel followed Hamilton home while Rosberg retired after his engine blew up with just two laps remaining.

Former Ferrari driver Felipe Massa crossed the line in third for Williams.

The win was the 40th of Hamilton's career and his seventh of the season.

When asked about the technical probe in the post-race press conference, Hamilton said: "I wasn't aware of it."

"This weekend has been fantastic," he continued. "I don't know if I ever had a weekend like this.

"This circuit is such a special one - and for all the drivers - when you stand on top of that podium you feel incredible pride and incredibly proud to be among the greats that have stood up there.

"The sea of fans is just like anything I have seen so it is very emotional when you are up there. I got a good start, I managed to hold ground and Sebastian was very fair into turn one. I was generally able to control if after that."
