BBC bosses and the show's creative team have opted to end the military drama series, following the departure of Michelle Keegan, who played the lead character, Lance Corporal Georgie Lane.

'Our Girl' creator Tony Grounds told RadioTimes.com: "With the finale of series four showing Georgie ready to move on with her life, it feels like the right time for us to do the same."

Despite this, Tony also admitted he'd be keen to reunite with Michelle, 33, at some stage in the future.

He explained: "Michelle and I are keen to continue our working relationship and, who knows, maybe we'll catch up with Georgie in the future.

"I wanted to say a big thank you to the fans of the show, it's been a joy to write."

Piers Wenger, the controller of BBC Drama, added: "We are very proud of Our Girl and would like to thank Tony Grounds, Michelle Keegan and the fantastic cast and crew for all their hard work on the show."

Michelle quit 'Our Girl' after series four of the drama, revealing she was keen to "explore other opportunities" in her career.

However, the former 'Coronation Street' actress also acknowledged that it had been a "really really difficult decision" to walk away from the show.

Michelle - who has been married to fellow TV star Mark Wright since 2005 - shared: "I just felt like I wanted to explore other opportunities.

"I've been doing it for four years now and I absolutely love the show, I really do and I love playing the character. I'm so going to miss it."
