The Global Coalition on Telecommunications (GCOT) represents a monumental effort to bolster telecommunications resilience, security, and innovation worldwide. With the UK at the forefront, alongside nations such as Australia, Canada, Japan, and the USA, this collaboration focused on overcoming critical challenges like cyber threats and supply chain disruptions. Central to the UK’s commitment was a substantial investment of £70 million into the Future Telecoms UKRI Technology Missions Fund (TMF) Programme, dedicated to advancing the next generation of telecom technologies domestically.

Facilitating this significant international partnership, Marnell’s role focused on influencing the broader strategy for telecommunications advancement. His efforts contributed to harnessing the collective expertise within GCOT, aimed at enhancing the resilience and security of communication networks worldwide.
