Lewis Hamilton cruised to his first Italian GP victory with ease, beating Sauber's Sergio Perez and championship leader Fernando Alonso.

Weekly talk about Hamilton's future has been heavy, linking the McLaren driver with a move to Mercedes. Yet he looked untroubled in victory from pole position, only losing the lead during a routine pit-stop.

Sergio Perez took full advantage of being able to choose which tyre to start on after qualifying 12th. The Sauber driver finished strongly on the faster medium-compound tyre, passing Alonso for second with seven laps remaining.

Fernando Alonso's thrid place finish from tenth, turned into a fantastic result when Sebastian Vettel retired with an alternator failure.

Alonso now leads the drivers' championship, 37 points ahead of second-placed Hamilton. Vettel's retirement drops him to fourth, two points behind Hamilton, one behind Raikkonen. 

The race was full of action with the main incident involving the two main title contenders at the time, Alonso and Vettel.

In his defence of an overtake, Sebastian Vettel was given a drive-through penalty for forcing Fernando Alonso off the track. The stewards decided that the German did not leave enough room for the Spaniard to pass.

The incident was almost identical to one involving the same drivers in last year's Monza GP. Vettel was forced onto the grass when trying to pass Alonso on the outside of Curva Grande, yet the stewards in this case decided Alonso had done nothing wrong.

After the penalty, Vettel rejoined the race behind team-mate Webber in seventh. He eventually passed Webber but was forced to retire with six laps remaining with his second alternator failure of the weekend.

Team-mate Webber completed Red Bull's miserable weekend when he retired on lap 52.

The Red Bull pair weren't the only high-profile retirements of the afternoon as Jenson Button's championship challenge all but ended with a retirement on lap 33. The 2009 champion sits in sixth place, 78 points behind leader Alonso.

The three retirements joined Jean-Eric Vergne back in the pit garages. The Toro Rosso driver suffered rear-suspension damage down to turn one on lap nine, and spun-out before flying through the air.  

One man who did have a very enjoyable race however was Sauber's Sergio Perez. He worked his way up the field from 12th, finishing on the podium in second place.

Perez started on the hard tyre, meaning he could finish the race on the faster medium tyre. The Mexican took full advantage and used his extra pace to pass both Ferrari's in the final stages, a fantastic drive and strategy from both Perez and Sauber.

Massa finished in fourth ahead of Raikkonen, Schumacher and Rosberg in fifth, sixth and seventh. Di Resta, Kobayashi and Senna completed the final three points positions respectively.

Lewis Hamilton's victory for McLaren was timely in a week of uncertainty for both driver and his team.

He sits second in the drivers' championship behind Fernando Alonso. The Spaniard didn't deliver a home victory for Ferrari at Monza yet will be more than happy after his title lead is consolidated further.
