News at Ten’s viewership is slightly boosted this week by the return of I’m a Celebrity get me out of here!

It was announced a few weeks ago that Mark Austin will replace Sir Trev on News at Ten.

Sir Trevor McDonald said: “I’ve tremendously enjoyed the opportunity to help re-establish News at Ten over the last year, but I’ve made no secret of the fact that I cannot be in the presenter’s chair forever. Anchoring ITV News’s live coverage of a hugely exciting and historic U.S. election seems the opportune moment to leave on a high.”

An ITV spokesman said McDonald will continue hosting the National Television Awards and working on ITV’s current affairs Tonight programme.

Crosby, will replace GMTV veteran Fiona Phillips, who announced her departure in September after 15 years.

Emma said: “I am very excited to be joining Britain’s leading breakfast programme and working alongside Kate, who is a great talent.”

Martin Frizell, editor of GMTV, said: “Emma will be joining us in the new year to share front line presenting duties with Kate Garraway.

“Together they will make up the best live presenting team in morning television.”

GMTV also announced the appointment of BBC weather presenter Kirsty McCabe to replace Andrea McLean, who is leaving after 11 years on the programme to take a permanent role on ITV’s Loose Women.

Both Crosby and McCabe will join in the new year.
