Candice first appeared as Sarah Platt's best friend from school. Candice was one of the first people Sarah told of her pregnancy. While many of Sarah's friends turned against her, Candice stuck by her throughout the pregnancy and birth of her daughter Bethany. She was Bethany's godmother. Her mother did not approve of Sarah when she became pregnant and called her a bad influence on her daughter, but it was later revealed that Candice was the bad influence on Sarah. Candice and her mother's relationship broke down when Candice's mother would not believe that she was being sexually harassed by her mother's boyfriend. Sarah's grandmother, Audrey Roberts, soon took pity on Candice and she moved into the salon flat. Candice then went on to work as a trainee hairdresser in Audrey's salon. Candice dated Todd Grimshaw, but he broke up with her after discovering that she had slept with Jason, his older half brother. When promising footballer Warren Baldwin arrived in Weatherfield she dreamed of fame and soon got together with him. But he later ended their relationship when he left to play for a Spanish team. Candice also dated Darren Michaels and Adam Barlow, but later dumped him via text message as she left the street when Status Quo offered her a job as a stylist.
Development
In June 2005, it was reported that Sanderson had quit her role as Candice. "I have had the most fantastic and memorable time here at Corrie," Sanderson said. She went on to say: "I made the decision to leave as it is time for me and Candice to leave the cobbles on a high. I am really sad to be going because I will miss everybody. I am excited about what the future holds and I'd like to thank everybody for the fantastic opportunities I have been given." Coronation Street producer Tony Wood said: "Candice is a character with a great deal of ambition and we felt it was not believable that she would stay in Weatherfield forever. At the same time Nikki has indicated that she wants to try her hand at other projects - it therefore suits Coronation Street and Nikki for the character to be written out this autumn. Nikki has been a real asset to the show and the writers have had great fun writing for Candice. We wish her all the bestfor the future." Following her departure The People claimed that Sanderson quit her role after becoming tired of being sidelined by the show's producers. She apparently felt that the soap's scriptwriters favoured her fellow cast-members Tina O'Brien and Samia Ghadie. The newspaper claimed that Sanderson told former boyfriend Jamie Meakin about her frustrations. "The whole thing about Nikki leaving Corrie for love and a singing career is really only half the truth and bit of a smoke screen," Meakin revealed. "She would say, 'I'm just as good as anyone else' and get all upset. To be honest, Nikki was jealous of the attention Tina and Samia got all the time." Sanderson later denied the rumours, explaining, "I've never felt sidelined by anyone. You only have to watch the show to see that I've had some fantastic storylines which I have thoroughly enjoyed. The only person who knows the real reasons why I'm leaving the show is me. I knew there would be speculation but to say things that aren't true hurts." In November 2011, the Daily Star revealed that Coronation Street producer Phil Collinson was planning on bringing back Sanderson and Tina O'Brien who played Sarah Platt between 1999 and 2007 in a bid to fill the gap left by the departures of Helen Flanagan who played Rosie Webster and Katherine Kelly who played Becky McDonald. A source told the paper: "He's aware that Sarah and Candice were hugely popular characters. He thinks it would be a ratings winner to bring them back. Losing Katherine and Helen is a big blow to the show so Phil wants to beef things up a bit with the return of a couple of big names." In May 2013, Sanderson who has since joined Hollyoaks playing the role of Maxine Minniver revealed that she has never considered reprising her role as Candice. Speaking to the Manchester Evening News, Sanderson said: "I've never even thought about going back to Corrie – I left seven years ago. I've done so many other things in that time. That's why it doesn't even feel like a crossover going into Hollyoaks, I've had a complete career between the two soaps." She continued: "Corrie was my first main job and I loved it, I loved being challenged. When I left Corrie I went on to a job where we were filming four or five scenes a day. I couldn't believe it, I was used to filming 16 scenes a day! I'd just assumed all TV work was like that." Following O'Brien's return as Sarah in 2015, Sanderson said to The Sun: "Tina's back on the cobbles, bless her. Could they tempt me back to the cobbles? No, I am loving it where I am at the moment."
