Sam Fender and Olivia Dean have achieved an unprecedented milestone in British chart history with their collaboration 'Rein Me In', which has now dominated the UK number one spot for 19 consecutive weeks. The achievement breaks a record that had stood for over seven decades, surpassing Frankie Laine's 1953 hit 'I Believe' which previously held the longest-running chart-topper status at 18 weeks. The song was first released as part of Fender's 2025 album 'People Watching' before Dean's featured vocal was added months later.

After a steady climb up the charts, the track reached the summit in February 2026 and maintained its position with remarkable consistency, with only four other major-artist releases briefly interrupting its run for single weeks each. The collaboration's commercial dominance was matched by critical recognition when it won Song of the Year at the 2026 BRIT Awards, cementing its cultural significance. Both artists celebrated the milestone, with Fender thanking Dean and fans whilst Dean marked the achievement by performing the song with Fender at her Lollapalooza headline set—the first time they performed it together in the United States.
