Lewis Hamilton silent over future

Lewis Hamilton has refused to answer questions about his future at McLaren at a press conference today.

Hamilton's future has been the subject of much speculation, with the 2008 world champion rumoured to be moving to Mercedes.

The 27-year-old is reported to have two final contract offers on the table from McLaren and Mercedes, but he refused to elaborate this afternoon.

"Before we start, I'm not here to speak about anything but the weekend," said Hamilton.

"I've no extra news for you, so use your time wisely to speak about other things if you can."

Hamilton is currently second in this year's Drivers' Championship.
