Alastair Campbell is a name synonymous with British politics.

He was Tony Blair's spin doctor and campaign director, and held much power during his time in Downing Street and in politics.

Even today, he's still an influential political thinker.

But during all of his years - he struggled with depression.

He's now told his story in his new book Living Better: How I learned to survive depression.

Alistair Campbell joined Mike Hosking for a chat.
