Due to the eliminations of 2 Shoes, Nu Vibe and The Risk, they were the only act left in their category. They were crowned the winners defeating Marcus Collins from the Boys category mentored by Gary Barlow. This made them the first-ever group to win the original show.
They are, along with One Direction and Fifth Harmony, one of the most influential bands to have partaken in The X Factor. They have had 3 subsequent UK Number ones ("Wings", "Black Magic", "Shoutout to my Ex"), a further 6 top 5 singles, and 21 top 10 positions in major charts with their albums, including 4 in the UK, with million selling albums "Get Weird" and "Glory Days", and 2 in the USA, where they were the first British girl group in history whose first album debuted in the Top 5, with limited promotion.
In November 2018, it was announced that they had parted ways with Syco Music and signed to sister label RCA Records, along with 2017 winners Rak-Su. This occurred just a few days before their release of their 5th album, LM5. The album was preceded by the single "Woman Like Me", with Nicki Minaj, which became their seventh Top 3 single on the UK charts. The group then had a controversial interview with Asos magazine in which they opened up to mistreatment and feuds with labels in the early stages of their career.
