Saturday Night Live UK made its debut on Sky last night, with American comedian and actress Tina Fey taking on hosting duties for the 75-minute premiere episode.
Isle of Wight indie duo Wet Leg served as the inaugural musical guest, while viewers were treated to unexpected cameos from Bridgerton star Nicola Coughlan, chat show host Graham Norton and Canadian actor Michael Cera.
The opening sketch featured cast member George Fouracres portraying Prime Minister Sir Keir Starmer attempting to dodge a telephone call from Donald Trump.
The programme was broadcast live from London with a cast of 11 comedians, including Hammed Animashaun, Larry Dean, Emma Sidi and Jack Shep, whose Princess Diana impression drew particular attention from critics.

The morning after its broadcast, overnight ratings revealed that the premiere pulled in 226,000 viewers, securing a 3.2 per cent share of the television audience at 10pm according to official Barb figures.
This represented a notable victory over Channel 4, which attracted 215,000 viewers for its broadcast of Mission: Impossible – Rogue Nation in the same slot — a rare achievement for any Sky programme.
The figures also dwarf those for Sky's long-running comedy sports quiz A League of Their Own, which drew just 60,000 viewers for its most recent series opener.
The UK version comprehensively outperformed the American original's British audience on Sky Comedy, where last week's Harry Styles-hosted episode attracted merely 4,550 viewers.

However, despite the ratings success, critical reaction to the premiere proved sharply divided.
The Telegraph awarded four stars, with reviewer Ed Power praising the "shockingly competent" spin-off and noting that Fey "shines as guest host."
He wrote that the show was "funny in places and never actively harmful to your emotional well-being," adding: "Against all reasonable expectations, this homegrown Saturday Night Live was more than capable of raising real laughs on its own."
Deadline's Baz Bamigboye took a starkly different view, describing the episode as "painful" and "a laughter-free yawn that's not a patch on Lorne Michaels' American original."

The Guardian and Independent both settled on three stars, with the latter observing that the debut demonstrated "a willingness to push the envelope, to risk bad taste."
Chortle's Steve Bennett was more enthusiastic, writing: "Whisper it, but I think they might just have nailed it."
The series returns next Saturday with Jamie Dornan taking on hosting responsibilities, accompanied by rock band Wolf Alice as musical guest.
Riz Ahmed has been confirmed as host for the third episode, with Kasabian providing the music.

Sky announced before the premiere that it had commissioned two additional episodes, extending the initial run to eight shows in total.
The programme will also reach American audiences, with episodes expected to stream on Peacock the evening after their UK broadcast.
The arrival of a British version of the 51-year-old American institution had been met with considerable scepticism, with many in the UK television industry questioning whether the format could justify Sky's substantial investment.
Previous attempts to create a British equivalent have historically struggled to gain traction with audiences.
