Affable presenting duo Ant and Dec collected three gongs at Tuesday's National Television awards, with Ant McPartlin thanking "best mate" Declan Donnelly for helping through "a tough year".

They took home best presenting prize for the 17th time, best challenge show for I'm A Celebrity ... Get Me Out Of Here! and the inaugural Bruce Forsyth Entertainment Award for Ant And Dec's Saturday Night Takeaway.

The duo made their first public appearance since McPartlin announced he was splitting from his wife, with the TV star saying that winning "really means a lot".

He said: "It's been a tough year for me personally, quite an emotional night so to kind of top it off with three awards has been ... can I have a lie down now? I'm feeling very good thank you."

On Donnelly, he said: "I love working with him and that was the one thing ... I had a very tough summer last summer, I had to face up to a lot of things and my one thing was just getting back to work and getting back to work with my best mate, we done it."

David Attenborough collects Impact Award for Blue Planet

Meanwhile, David Attenborough delivered a powerful speech after his BBC series Blue Planet was honoured with the Impact Award at the ceremony.

The veteran broadcaster took to the stage where he urged people to "protect our beautiful world".

He said: "We would far rather there wasn't a problem, we would far rather that we could make a programme about the splendours and beauties of the sea, that's what we set out to do but if you did that with any degree of conscience you had to do what we ended up doing.

"We are greatly happy that what these people have been doing should be seen so worldwide and what is really a world problem is taken notice of around the world."

Suranne Jones wins drama performance for Doctor Foster

Suranne Jones won the drama performance award for her role as Doctor Gemma Foster in Doctor Foster, while the show itself won the best drama prize.

Jodie Whittaker, the first ever female Dr Who, was among the victorious Broadchurch cast who won best crime drama.

Both actresses showed their support of equal pay with Jones sporting a 50/50 badge backing equal representation for women. Following Broadchurch's win, Whittaker said: "It's an incredibly important time and the notion should be supported."

She added: "It's a bit of a shock that it's a surprise to everyone that it should be supported. I know I do not speak just on behalf of the women here, I speak on behalf of the men and the women."
