Irish actor Stephen Rea and presenter Graham Norton were victorious at the TV BAFTAs this evening while fellow Irish stars Chris O'Dowd and Brendan O'Carroll lost out in their respective categories.
Rea was the first actor and Irish star of the night to scoop an award, picking up a coveted gong for his role as Sir Hugh Hayden-Hoyle in the BBC Two's The Honourable Woman.
He beat rivals Ken Stott from The Missing, Adeel Akhtar from Channel 4's Utopia and James Norton from Happy Valley for Best Supporting Actor.
"There are so many incredible actors in the Honourable Woman. I feel I'm receiving this on their behalf," he said.
Fellow Irish star and TV BAFTA presenter Graham Norton called his team from The Graham Norton Show on stage to join him accepting the award for Comedy and Comedy Entertainment, the award they won over competition Charlie Brooker's Weekly Wipe, Stewart Lee's Comedy Vehicle, and Would I Lie To You.
He then shooed them off stage and said: "Yay me!".
The comic had opened the ceremony with a string of one-liners to get the celebration started after what he called "election fatigue".
He quipped: "We bid farewell to Clegg, Milliband and Farage. On the upside, the makers of Top Gear have just had an idea."
Norton lost out on Entertainment Performance to Ant and Dec prompting Norton to quip, "Delighted for them!".
They were also up against Leigh Francis for Celebrity Juice and Claudia Winkleman for Strictly Come Dancing in the category.
Earlier the comedy duo had also won Best Entertainment Programme for their ITV show Saturday Night Takeaway.
Picking up the gong, Ant told the audience: "What a great start to the show - for us. We're delighted with it, thrilled. We love making this show."
Irish star Chris O'Dowd's Moone Boy was up for Scripted Comedy but lost out on the night to Detectorists which also proved victorious over Harry and Paul's Story of the Twos and The Wrong Man.
Also missing out for the Irish contingent was Brendan O'Carroll who was beaten by Hugh Berry who won Best Male Performance in a Comedy Programme.
O'Carroll was up for Mrs Brown's Boys Christmas Special while Berry won for Toast of London. They were up against Hugh Bonneville for W1A and Tom Hollander for Rev.
Sherlock might have won a gong for Radio Times Audience Award but Benedict Cumberbatch again missed out on a television Bafta for his portrayal of the master detective.
Instead the leading actor role went to Jason Watkins for his portrayal as the murder accused in ITV's drama the Lost Honour of Christopher Jefferies.
It was Cumberbatch's third nomination for his performance in the hit BBC show.
Watkins said later: "I can't believe it. It's very satisfying to be nominated and to win - I just can't believe it."
Georgina Campbell was a surprise win of the night after claiming leading actress award, which had been largely tipped to be taken by Sheridan Smith.
The young actress won for her portrayal of a domestic violence victim in BBC 3's Murdered by My Boyfriend.
Shaking as she picked up her gong the little known actress said: "This is insane. The women who are in this category are absolutely brilliant.
"If I have the career they have in a few years time I will count myself very, very, lucky."
BBC bosses will be left red-faced by the win - just as the corporation moves to axe the digital channel and replace it with an online-only service.
Comedian Jessica Hynes used her win for Best Female Performance in a Comedy Programme to make a stand against ongoing austerity cuts.
The actress who won her award for playing Siobhan Sharpe in W1A told the audience to rapturous applause: "I'm from a single parent family. I'm really worried about the cuts that are coming in state education and to people in low income families. Because I don't feel low income means low talent, low imagination or low intelligence."
Foreign reporter Alex Crawford was part of the Sky News Live at Five team which picked up the gong for best News Coverage, for their "brave" reports on the Ebola epidemic.
New mother-in-law Judy Murray took to the stage in a glamorous sheer panel dress to present the award for Sport and Live Event which went to the BBC for their coverage of the First World War remembrance celebrations last year.
Grand Designs presenter Kevin McCloud thanked the "millions and millions of loyal fans" who have followed the Channel 4 programme "for the past 20 years" as he collected the award for Best Feature.
In the international category, HBO series True Detective beat The Good Wife and Netflix series House of Cards and Orange is the New Black.
An emotional and clearly shocked Gemma Jones was close to tears as she picked up Best Supporting Actress for her portrayal of Mary Baldwin in Marvellous .
The bio-pic told the true story of Neil Baldwin, who refused to accept the limitations of his learning disability.
It was her first nomination for the veteran actress since 1997. She told the audience: "I'd like to thank the real Neil who so generously allowed us to intrude on his extraordinary life."
The soap war was again won this year by ITV's Coronation Street whose production team proudly collected the Soap and Continuing Drama award.
It was despite Eastenders' gripping "whodunnit" plot around the murder of Lucy Beale.
