Early Career and Conservative Party Foundations
Building Campaign Expertise (1988–1992)
Mark Fullbrook began his senior political career within the Conservative Party in 1988. Rising to become Deputy Head and later Head of Campaigning, he played a central role in shaping electoral strategy during a highly competitive political period.

The Conservatives defied many polling expectations and secured victory with more votes than any UK political party had ever received at the time. He was involved in managing target seat operations and coordinating communications efforts that proved decisive. This experience established him as a serious operator within political strategy circles.
The Creation of Parliamentary Liaison Services
In 1993, he founded Parliamentary Liaison Services Ltd (PLS), a political communications consultancy focused on supporting Conservative causes and clients. As Founder and Managing Director, he led the organisation for over 17 years.
During this period, he refined his expertise in targeted messaging, stakeholder management and reputation strategy. His consultancy provided advisory services that blended political understanding with practical communication techniques. This long tenure in private practice gave him commercial insight alongside his political background.
