It seems humiliating for McLaren to be going back to Mercedes engines when it doesn't seem like many years ago it was ditching them. Do you think this switch will actually help? Surely three changes of engine supplier in quick succession can only disrupt the team, and Williams isn't exactly thriving with Merc power.

I don't think it's humiliating. McLaren changed from Mercedes to Honda for the right reasons because it wanted to win, and competing against the works Mercedes team using the same engine meant that would be very difficult.
