I stand here knowing that my story is part of the larger American story, that I owe a debt to all of those who came before me, and that, in no other country on Earth, is my story even possible," Obama said that evening.

Wednesday 21 August: The former president Bill Clinton will join the Minnesota governor and nominee for vice-president, Tim Walz, on the convention's third night.
