Strictly Come Dancing 2019: When does it start? Who are the celebrities? Who are the judges? All you need to know

The Glitterball Trophy is being polished ready for the start of the next series. Find out when it starts and who's likely to be stepping out onto the dancefloor.

It’s that time of year again – the celebrities are being spray-tanned, the sequins are being stitched to costumes, and the dancers are tapping their toes in anticipation of a new contest.

Strictly Come Dancing is returning for a 17th series and the excitement is building to find out who will be taking part, who will be matched with which professional, and who will be in the final.

Here’s all we know so far about Strictly 2019.

When is Strictly Come Dancing back on TV?

Cancel your Saturday night plans for the forseeable - BBC One has announced that the Strictly launch show will air on September 7.

Although we think of it as a winter series, the Strictly machine starts gearing up in the summer.

The celebrity contestants were revealed, one or two at a time, from August in preparation for the launch show at the start of September, when we’ll see the couples matched with their professional partners.

Strictly then takes a break for a couple of weeks while the dancers get rehearsing, ready for the live shows to begin on Saturday evenings on BBC One with a pre-recorded results show aired on Sundays.

If the series follows the schedule of previous years, we’d expect the live shows to begin from September 21.

Who are the judges and presenters?

The biggest story so far in Strictly 2019 is who will replace judge Darcey Bussell.

Ballerina Darcey announced in April that she planned to leave her role after seven years on the panel, leaving a coveted spot on one of the biggest shows on TV open.

The woman taking her seat has been revealed as Motsi Mabuse, sister of Strictly favourite Oti, a fellow ballroom dancer and judge on Let's Dance, the German version of Strictly.

Anyone who's worried that the sisters might find it awkward with Motsi judging Oti should know that Oti has competed in two seasons of Let's Dance with her sister on the judging panel, and certainly received no favours from her sister, who scored her three out of 10 for one routine.

Former judge Alesha Dixon ruled herself out of the running, as did Motsi's sister Oti despite her recent turn as a judge on The Greatest Dancer. Pro dancer Anton Du Beke was touted as one of the strongest contenders for the job, but he will be back in a performance role for another year.

Darcey’s ex-colleagues Bruno Tonioli, Craig Revel Horwood, and head judge Shirley Ballas will all be returning.

We’re also expecting to see popular duo Tess Daly and Claudia Winkleman back to front the programme.

Which celebrities are taking part?

We've now had the full line-up of 2019 celebrity contestants announced, and there's someone for everyone to get behind in 2019.

Anneka Rice, James Cracknell and David James are amongst the bigger names signed up for this year, but the producers have also included soap actors, reality TV stars, and another YouTuber in the mix.

EastEnder Emma Barton and former Corrie regular Catherine Tyldesley will compete alongside Jamie Laing, Michelle Visage, and comedian Chris Ramsey.

The BBC has brought in its own stars with sports presenter Mike Bushell, CBBC star Karim Zeroual, and radio DJ Dev Griffin.

Former Lioness Alex Scott and Paralympian Will Bayley are upping the sports quota, while the lesser known contestants are Viscountess Emma Weymouth and YouTuber Saffron Barker.

Which professional dancers are returning?

A cast list of 17 pro dancers has been announced, although it isn’t yet clear who will get a celebrity partner and who will be part of the larger troupe.

There is one new name added to the list this year – the only other change is that Pasha Kovalev isn’t included after announcing earlier in the year that he was quitting after eight years competing on the series.

Who is the new professional dancer?

The Strictly family has welcomed one new dancer this series - Nancy Xu, 28.

Nancy is from China and was a finalist in her home country's series of So You Think You Can Dance?, as well as being part of the West End and Broadway cast of dance show Burn the Floor.

She's picked up many a trophy in Latin dance contests, and said: “I'm thrilled and excited! I cannot wait to start this new journey with all these amazing people and share the magic together.”

Strictly Come Dancing returns to BBC One on September 7.
