Mark Feehily (Mark from Westlife) has been publicly detailing health challenges that affected his ability to tour with the band in 2024–2025. In late 2021 he experienced pneumonia, required surgery, and subsequently faced ongoing health issues that led him to step back from touring to focus on recovery and his well-being. The band has stated that he remains an integral member of Westlife and continues to contribute to new music and the group’s projects, even though he has not joined them on the live anniversary tour segments. Updates around late 2025 indicate he is still prioritizing his health, with the band acknowledging his ongoing involvement in the group and occasional appearances or contributions, but not full participation in touring at that time.
