Adolescence has made Bafta history as it completed its winning streak through awards season, taking top prizes at the awards, where Celebrity Traitors also triumphed.

The hit Netflix drama, about a teenage boy accused of a terrible crime, claimed four awards, the most won by a single TV series in the main ceremony.

It was named best limited drama, while stars Stephen Graham, Christine Tremarco and Owen Cooper all won awards.

Graham was named best leading actor, Tremarco won the supporting actress prize and Cooper took supporting actor.

Graham, who co-wrote the script with Jack Thorne, has won a string of awards for his performance in the Netflix series, including an Emmy and a Golden Globe, but had never won a Bafta.

Speaking on stage, he said: “I might take my time. I’ve been nominated eight times and this is the first time I’ve won.

“Nice one Bafta, this is lovely.

“We’re not digging holes, we’re not digging ditches, we’re not saving lives, but we have the opportunity to tell the human condition, and we have the obligation to tell beautiful stories and we need to keep that going.”

Cooper (16) who has also proved unbeatable through awards season, won the first prize of the night and said: “A year ago, I was presenting an award and now I’m collecting one. This is a bit mad.”

He added: “In the words of John Lennon, you won’t get anything unless you have the vision to imagine it.

The Graham Norton Show was also nominated in the entertainment programme category, although Graham Norton, a serial Bafta winner, missed out on a nomination in the entertainment performance category.

Celebrity Traitors won the best reality award, as well as the memorable moment prize, for Alan Carr’s treacherous victory.

Collecting the award, he said: “Was I good? Was I really? Or were the other celebrities just thick?

“It was Nick [Mohammed] who made me cry – we were round that round table and he went, ‘We’ve got this’, and I was like, ‘No, I’ve got this’.

“When I laughed in their faces and went ‘I’m a faithful’, I was packing my bags. But I had the best time ever.”

Comedy show Last One Laughing won two awards, for entertainment programme and entertainment performance for Bob Mortimer.

Hit BBC comedy Amandaland won the prize for best scripted comedy.

The leading actress Bafta was won by Narges Rashidi for her portrayal of Nazanin Zaghari-Ratcliffe in Prisoner 951.

Dedicating the prize to the British-Iranian woman who was imprisoned in Tehran, and her family, Rashidi said: “Your resilience, your dignity, your love through impossible circumstances have moved us all.

“Your courage will stay with me for the rest of my life. This is for you.”

She added: “I was a seven-year-old who survived war. In Gaza, in Ukraine, in Sudan, they may never get that opportunity, that chance.”

Leading actress in a comedy was won by Katherine Parkinson for Here We Go, while leading actor in a comedy went to Steve Coogan for How Are You? It’s Alan (Partridge).

During his speech, Coogan pledged to play Partridge for the rest of his life, saying: “Doing comedy in these troubled times is so important. It’s a privilege to make people laugh after all these years.

“I will keep on doing it. If anyone wants to know when Alan Partridge is going to die, it’s about the same time that I am going to die.”

EastEnders was named best soap, while US comedy The Studio was named best international.

Code Of Silence, starring Rose Ayling-Ellis as a deaf canteen worker who helps police with a dangerous investigation using her advanced lip-reading skills, called on the TV industry to improve representation, saying: “The industry needs to improve and hopefully it will.”

Gaza: Doctors Under Attack, the documentary commissioned and then shelved by the BBC over impartiality concerns and later aired by Channel 4, won the current affairs Bafta.

During his speech on stage, executive producer Ben de Pear referred to the fact the BBC airs the ceremony on delay, saying: “Finally, just a question for the BBC: given you dropped our film, will you drop us from the Bafta screening later tonight?”
