Alison O’Donnell, who has played DS Tosh McIntosh on the BBC crime drama Shetland for more than a decade, confirms she is leaving the series after 13 years. Multiple outlets report that her departure has prompted speculation about who could take over her role in future seasons. The Mirror and Manchester Evening News both cite actor Ralf Little as a name being tipped for the replacement, describing him as a “favourite” or “tipped” option. Both reports frame the development as casting discussion rather than an announced deal, noting that the identity of O’Donnell’s successor has not been formally confirmed by the BBC. The coverage focuses on the impact of O’Donnell’s exit on the show and the early conjecture surrounding potential replacements as Shetland prepares for the next chapter without her.
