Lewis Hamilton demands answers from Mercedes after enginge failure in Malaysia

Lewis Hamilton dramatically turned on his Mercedes team by appearing to hint at a conspiracy theory after his bid to win a fourth championship was left hanging in the balance following yet another engine failure.

Hamilton was on course to cruise to the 50th victory of his career in Malaysia and move at least five points clear of his sole rival Nico Rosberg, who fought back to finish third following a first-corner collision with Sebastian Vettel, in the championship race.
