LONDON (Reuters) - Lewis Hamilton's new Formula One deal has ended speculation about his plans for this season but the one-year duration raises questions about how long the seven times world champion will stick around.

All of the 36-year-old Mercedes driver's previous deals have been multi-year agreements but a shorter one buys time for both sides while other issues are worked through.
