Lewis Hamilton stripped of Belgian Win - Belgian Grand Prix

Hamilton leads at the first corner in the McLaren while Kimi Raikkonen claims second spot from Ferrari team-mate Felipe Massa

McLaren's Lewis Hamilton was stripped of a dramatic victory in the Belgian Grand Prix after stewards handed him a 25-second post-race penalty.

The Englishman was demoted to third place behind Ferrari's Felipe Massa and BMW Sauber's Nick Heidfeld.

He was accused of gaining an advantage by cutting the Spa circuit's Bus Stop chicane in a late-race battle with Ferrari's Kimi Raikkonen.

McLaren announced that they intend to appeal against the stewards' decision.

The demotion meant Hamilton's lead over Massa in the title chase cut to two points.

Massa's team-mate Raikkonen, who crashed out of second place shortly after losing the lead, is 19 points behind Hamilton.

Raikkonen is a point behind BMW Sauber's Robert Kubica.

Before the penalty, Hamilton had extended his lead over the Brazilian to eight points, with Raikkonen effectively out of the running on 23.

On the track, Hamilton had survived a frantic last two laps in a late shower of rain to apparently score a superb win.

Hamilton lost the lead to Raikkonen with an early spin but fought back in the closing laps to re-take the lead with two laps to go.

In a dramatic climax on a soaking track, Hamilton passed Raikkonen, lost the lead again with a spin, re-took it and then saw Raikkonen crash.

In a chaotic final couple of laps, Heidfeld jumped from eighth to third place on the track with what he called a "hero or zero decision" to come in for wet-weather tyres with two laps to go.

Renault's Fernando Alonso chose the same tactic a lap later and it secured the double world champion the fourth place he had held for much of the race.

"It was an experience and a half," Hamilton said before his penalty was announced. "I was praying for rain. I wanted it to come because I knew how to deal with it.

"The heavens opened and I saw Kimi begin to back off and to brake a bit earlier.

"I was going reasonably wide at Turn 12 but Rosberg spun and went off where I was coming back on. I went over the grass. It was incredibly tough.

"Kimi pushed me wide. I was a little bit ahead. I was outside on Turn One, I had no room and he basically pushed me so I went on the escape route.

"So I let him past, then got in his tow and he was ducking and diving left and right but I managed to get past him and I was pretty much gone from there."

It was another superb performance in the wet from Hamilton, who has inherited Michael Schumacher's mantle as Formula One's rain master.
