The show sees Caroline star as headteacher Louisa Martin, the wife of the strangely lovable Doctor Martin Ellingham, played by Martin Clunes.

Continuing to gush about the show, the star said: 'For me, one of the appeals of Doc Martin is that it inhabits an entirely credible make-believe world with its own rules, sense of time, space and even fashion.

There’s this amazing, expansive landscape, which feels so free and open, yet you’re constantly drawn back to the epicentre of the village, where you can’t even blow your nose without everyone knowing about it. And you can’t get away, no matter how hard you try,’ she continued.
