AceShowbiz - Sam Fender and Olivia Dean have extended their dominance on the U.K.'s Official Singles Chart as their hit Rein Me In secures a fifth non-consecutive week at No. 1, according to the chart dated March 27, 2026.

The track originally reached the top spot in February and currently stands as the longest-running No. 1 single of 2026. This milestone marks Fender’s first chart-topping single in the U.K. and Dean’s second. The song also earned critical acclaim at the 2026 BRIT Awards, winning the fan-voted Song of the Year category.

Rein Me In first appeared on Fender’s Mercury Prize-winning album People Watching, released in February 2025. Several months later, the North Shields singer and Dean released a new version of the song together after performing it live at Fender’s sold-out show at London Stadium.

Meanwhile, BTS achieved their highest U.K. chart position with their single "Swim," which rose to No. 2, surpassing their previous peaks with "Dynamite" (2020) and "Butter" (2021), both of which reached No. 3. "Swim" is BTS's fifth top 10 hit in the region. Their comeback album ARIRANG debuted at No. 1 on the Official Albums Chart, and two other tracks from the album, "Body to Body" and "FYA," placed at No. 28 and No. 39 respectively.

In the rest of the top five, Bella Kay’s breakout single "Iloveitloveitiloveit" slipped one position to No. 3, followed by Harry Styles’ "American Girls" at No. 4, and PinkPantheress’ "Stateside" at No. 5. Notably, a remix of "Stateside" featuring Zara Larsson recently reached No. 1 on the Global 200 chart.

Other notable chart movements include Dominic Fike’s "Babydoll" climbing to No. 11 and "White Keys" reaching No. 17. Tame Impala’s "Dracula" moved up to No. 12, while RAYE’s collaboration with Hans Zimmer titled "Click Clack Symphony" debuted at No. 18.

With Sam Fender and Olivia Dean continuing to hold strong at the top of the U.K. singles chart, their collaboration on Rein Me In remains a defining moment in 2026’s music landscape.
