Bruce Forsyth has pulled out of Saturday's Strictly Come Dancing "on doctor's orders" because he has flu, the BBC has announced.
Co-presenter Tess Daly will be taking on the 81-year-old's hosting role while her backstage duties will be handled by Claudia Winkleman.
Winkleman presents spin-off show It Takes Two on BBC Two.
It is the first time Forsyth has missed a show since Strictly Come Dancing began on BBC One in 2004.
"Unfortunately, due to a bout of the flu and on doctor's orders, Bruce will be unable to host Strictly Come Dancing this Saturday.
"However, Tess Daly will be stepping into his presenting shoes," a spokesman said.
