Strictly Come Dancing viewers were shocked tonight as presenter Alison Hammond made a surprise appearance. 

Hammond previously competed on the show in 2014, but tonight made a surprise appearance to read out the voting terms and conditions for tonight's show. 

Hammond appeared backstage with Claudia Winkleman wearing a "vintage 2014 Strictly" dress that she wore when she competed in the show.

Viewers who watched the exchange called the presenter a "national treasure", while others called for her to be one of the show's hosts.

One user wrote on Twitter: "if we all just start calling Alison Hammond "Dame Alison Hammond" they eventually just have to accept it as fact #scd #strictly"

Another said: "Give us an All Stars and give us the return of @AlisonHammond to that dance floor. #Strictly"

What time is the Strictly Results show?

The Results show will follow on Sunday at 7.15 pm, also airing on BBC One.

Who left Strictly Come Dancing last week?

EastEnders actor James Bye became the fifth celebrity to leave Strictly last week.

The 38-year-old proclaimed that he had made a “friend for life” in his dance partner Amy Dowden as he exited the competition.

The soap actor, who has played Martin Fowler in the BBC series since 2014, performed a charleston dressed as a beekeeper to the song Bumble Bee by LaVern Baker.
