MPs offices are like "650 tiny kingdoms", with just one or two people working very closely together, and little external oversight. So, if something goes wrong with a work relationship, MPs staff can feel like they have no-one to turn to for help.

On the second episode of this three-part series, Sky's political correspondent Liz Bates speaks to Parliamentary staffers who lived in fear of the MPs they worked for, developed post-traumatic stress disorders and some who were forced out of the jobs they loved due to bullying.
