The BBC made things difficult when they spent so much of our money relocating to Salford. If people wanted to keep their jobs, like Susannah, they had to do a horrible commute if their children were settled in schools and partners in jobs and they didn't want to move. And I think Strictly takes up so much of a contestant's life that the rest of the family would have to be extremely understanding and well able to cope.
I feel sorry for them all, especially the children. I wasn't on GN so never heard of grandmaminey, but we always like Susannah on Breakfast. It's just a change of job, sometimes the press makes it sound like a defection if people move from BBC to ITV!
