Coming very soon is the new series of Hotel Babylon on BBC1. Scraping around Wikipedia shares a lot of info on this including Emma’s character leaving during this 4th series.

Taken from Wikipedia:

Anna slept with Charlie shortly before they began their current jobs and, during the first series, narrowly avoids being sacked after having sex with a guest then taking his money. During the second series she gatecrashes a party after stealing a costume from the duchess of Cirencester. She also dresses up as a reporter to an actor.
