From their website:
Westminster Skills Centre was founded in 2019, by a group of people who have worked in and around Westminster for decades. From personal experience we know how complex Westminster can be, and also how little high-quality training exists to explain how things really work. Our mission is to provide outstanding development opportunities for staff and politicians from all political parties, as well for those working in business and civil society. We believe this increased understanding will ultimately lead to more effective decision-making.
We offer a range of one day and half-day courses, many of which are designed to explain how Parliament works, how legislation is passed and how to run an effective political campaign.
