After 10 wonderful years & 11 series, Sir Bruce Forsyth has decided to step down from the rigours of presenting our live shows.
The 86-year-old added: "It comes to a time when you do get to a stage and say 'this is enough'. And I do get tired doing live telly. Live telly is very, very strenuous, especially when some of the shows are an hour and 40 minutes long."
"It was a big decision... It's better for me physically, I'll be able to spend more time with my wife and my family."
