Sir Terry Wogan has taken doctor’s advice and withdrawn from tonight’s Children in Need fundraiser on BBC1

The 77-year-old semi-retired TV presenter is having a procedure on his back and his doctor has advised against participating. It will be the first Children in Need he hasn’t presented since it launched in 1980.

He told the BBC he would miss ‘our wonderful, inspiring evening’ but would still be ‘watching, cheering and donating’.

He will be replaced as host by Dermot O’Leary.

The BBC said: “We are incredibly grateful to Dermot for stepping in at such short notice but know he’ll do us and Sir Terry proud.”

Dermot said: “It’s a huge honour to be asked to step into Sir Terry’s shoes tonight; he is one of my broadcasting heroes and has been a source of support for me down the years.

“I’d like to add my best wishes to Sir Terry for a speedy recovery, and I hope I do him justice and do my small part to make the night a success and make as much money as we can for disadvantaged children across the country.”

Tess Daly, Rochelle Humes, Nick Grimshaw and Fearne Cotton will join Dermot in presenting Children in Need.
