F1: Lewis Hamilton not expecting McLaren to sacrifice Jenson Button

Hamilton chalked up his third win of the season and 15th of his career to move three points clear of Mark Webber with six races remaining.

In stark contrast to Hamilton's jubilation, reigning world champion Button was left feeling despondent after he crashed out for the second successive season at Spa, and again not of his own making.

Button was on course to finish runner-up when he was speared from his left-hand side by an out-of-control Sebastian Vettel in his Red Bull who had misjudged his braking in attempting to overtake.

With the radiator punctured and drive lost, Button was forced to retire, and with Hamilton going on to victory he is now 35 points adrift of his fellow Briton.

Yet with 150 points still up for grabs, Hamilton knows McLaren will not favour himself over Button until the situation dictates otherwise.

"I get the same treatment as Jenson and vice versa and that enables us both to score maximum points and so I don't feel there should be any preferential treatment," said Hamilton."

Hamilton has also dismissed the suggestion the title race is now just between himself and Red Bull's Webber who had to be content with second after starting from pole.

Along with Button, Vettel and Fernando Alonso also failed to score a point, with the German finishing 15th and the Spaniard crashing out in the wet late on.

Hamilton is now 31 points ahead of Vettel, yet despite the cushion he added: "You've seen in the last few races how quickly things can change.

"We still have a long way to go."
