The 59-year-old star plays DI Geordie Keating in the ITV detective drama and revealed how he was taken aback to find out that the programme has a big fanbase in Australia.

Robson is quoted by the Daily Mirror newspaper as saying: "I just came back from doing a fishing show in Australia. In the outback I was with what I'd call really stereotypical Australian blokes, who told me 'Grantchester' was their favourite show!

"Wow. I feel honoured and privileged to be part of something that is enjoyed around the world."

The eighth series of 'Grantchester' begins on ITV next month and Robson explained that he has no intention of leaving the show even though co-stars James Norton and Tom Brittney have both opted to move on.

He told Radio Times: "As I'm in the last third of my life, I want to work with people I love working with and do projects that make me genuinely happy and push me creatively.

"But in the end, I just want to really have fun doing what I love. And 'Grantchester' caters for those needs.

"I'm an executive producer, and at the beginning we knew we had something special and that would float the audience's boat, but we never realised how popular it would turn out to be and how well it would be received around the world."

Robson had promised that the upcoming series will feature some "gripping" stories as the unlikely duo of DI Keating and Reverend Will Davenport (Brittney) team up to solve more crimes.

He said: "There’s a murder every episode and the stories are really gripping.

"We start with a case where a biker is found dead in a field after a charity motorbike race. Geordie and Will both realise this is a murder and not an accident. Then Will gets involved in a tragedy where somebody loses their life and Geordie desperately wants to exonerate Will."
