Sarah Harding

Sarah Harding moves through the corridors of Westminster as one of the many watchful figures orbiting Francis Urquhart's rise, alert to the currents of ambition and secrecy around her. She observes more than she declares, feeling out where power is shifting and what it might cost to get close to it.

Kitty Aldridge brings a controlled, attentive presence to a drama built on unspoken calculation, letting small shifts of expression carry the weight of what her character notices but won't yet say. In a show where every glance is a move, that restraint makes her feel dangerous in the quietest way.
