JK Rowling breaks down in tears when she returns to the flat where she wrote the first Harry Potter book, and admitted that even after a decade of phenomenal success, she still sometimes struggles to believe her current life is real.

The moment was captured during filming for JK Rowling...A Year in the Life, transmitting on Sunday 30th December at 7pm on ITV, as Jo, returning for the first time to the flat in Leith, Scotland, where she began writing the Harry Potter saga, was overcome with emotion on facing the 'ghosts' of her past - the struggle she endured during her early writing.

The flat is only a few miles from her main home in Edinburgh, yet she had never gone back there before.

Stepping in to the front room of the flat Jo says: "This is really the room where I finished Philosopher's Stone, here. This is really where I turned my life around completely. My life really changed in this flat."

Jo explains further: "I feel I really became myself here, in that everything was stripped away, I'd made such a mess of things. But that was freeing, so I just thought, 'Well, I want to write,' and I wrote the book and, 'What is the worst that can happen? It gets turned down by every publisher in Britain, big deal. It's really back to the wall time here.'"

As she walks around her old home she is amazed to find copies of the Harry Potter books in what was her bedroom, but is now occupied by new residents.
