Major Royal is replacing Holly Willoughby as host of This Morning – but only for one day

SARAH Ferguson is replacing Holly Willoughby as a host on This Morning — for one day.

The Duchess of York, 64, will join Alison Hammond and Dermot O’Leary on the sofa on Monday.

Fergie, 64, is also editing the ITV1 show from the gallery — with segments including how to rehome a dog and an interview with Sir Cliff Richard.

She has appeared as a guest before but said: “I’m looking forward to being there for the whole morning, and thrilled to be guest editing the show which will mean getting to explore some topics I’m passionate about.”

Fergie — mum to Princesses Beatrice, 35, and Eugenie, 33, with ex Prince Andrew, 63 — is also overseeing features on skin protection and the importance of defibrillators.

This Morning boss Martin Frizell said: “I’m very happy for her to make some of my decisions on Monday.

“She has a great understanding of the show.”

Holly, 42, quit last month.

Fergie had been teed up for I’m A Celebrity but talks collapsed when she refused to discuss Andrew, with whom she still lives.

• This Morning airs weekdays from 10am on ITV1 & ITVX.
