The South African dancer told fans that she “can’t put in to words how difficult this decision has been” in a social media post confirming the news.
In a statement, the hit BBC dance competition stated: “Oti has been a truly wonderful part of Strictly for the past seven years. Her energy, creativity and talent have contributed to so many of the show’s most memorable moments and she will be hugely missed, not only by viewers but the entire team.
“She leaves a dazzling legacy behind her, as the only professional dancer to lift the Glitterball Trophy in two consecutive years.”
Mabuse joined the series in 2015, winning the competition twice: in 2019, with celebrity partner Kevin Fletcher, and in 2021, with Bill Bailey.
“We couldn’t be prouder of Oti and what she has achieved,” continued the official Strictly statement.
“She will always be at the very heart of our Strictly family and we wish her every success in her already bright future.”
Mabuse addressed her departure from the series on Instagram, telling followers it was “never easy to say goodbye”.
“I have been part of the most amazing TV show, Strictly Come Dancing, for the past seven years and it has been an incredible time.
“Lifting the glitter ball twice and having the best journey with all my celebrities, but also meeting and working with the best team, crew, producers, celebs and incredible professional dancers! You are my family and I adore you all forever.”
