Raine as Alison Laithwaite, in The Last Post.

Viewers in the UK are reportedly quite shocked, to see Raine in such a controversial role, after rising to fame as the straight-laced Jenny in TVNZ 1’s Call the Midwife.

The two period dramas might be set in a similar era, but the characters couldn’t be more different.

Jenny could be described as a saintly nurse – Alison, on the other hand is an alcoholic adulterer, with a sharp tongue and a wicked sense of humour.

Her character has been described in the British media as “gin-soaked and sex-crazed.”

The first episode of The Last Post sees her in bed with her husband’s military superior. And she’s rarely spotted without a drink in hand.

Alison clearly has some secrets, some reasons for her self-destructive behaviour.

We’re excited to watch her story unfold as the series continues.

Raine was excited about her sexy new role, saying “I got a real hit of Alison as soon as I read the script.”

“After a few weeks of playing her, I have this overwhelming desire to go out, get drunk and fling myself around a dancefloor.”
