Andrew Yorston

General Counsel | VodafoneThree

Team size: 310 across Legal, Security, Compliance and Risk

What are the key projects you have been involved in over the past twelve months?

The most significant project over the past twelve months has been supporting the successful integration and establishment of VodafoneThree following the completion of the £15bn merger between Vodafone UK and Three UK on 31 May 2025. As general counsel, I have played a central role in leading the legal, regulatory, compliance and governance activities required to bring together two major organisations and create a single, high-performing business.

Since completion, my team and I have been at the heart of the integration programme, designing and embedding the governance framework for VodafoneThree, ensuring that VodafoneThree policies and processes were in place, managing complex legal entity and operational integration activities and negotiating and implementing strategic agreements. We have continued to work closely with government stakeholders, regulators and industry bodies as VodafoneThree delivers on its commitments to invest in and transform the UK’s digital infrastructure.

Alongside the merger, my team has supported the business across a broad range of strategic priorities, including artificial intelligence (AI) and digital transformation initiatives, major enterprise customer relationships, security and regulatory engagement, sustainability partnerships and large-scale commercial programmes. We have also continued to manage significant litigation and dispute matters while supporting business growth and transformation activities across the organisation.

Please provide a brief description of any internal transformation/development projects within your legal team over the last twelve months.

The past year has been one of significant transformation. Bringing together two large organisations required not only the integration of legal teams, but also the harmonisation of policies and processes, governance frameworks, ways of working and organisational culture.

A key focus has been leveraging technology and AI to improve efficiency and enhance the services we deliver to the business. We have piloted and adopted emerging tools that support contract authoring, legal drafting, negotiation and risk analysis. We have also encouraged practical experimentation with generative AI while ensuring appropriate governance, security and regulatory controls are in place.

Equally important has been building a high-performing and inclusive culture. I have strengthened our focus on wellbeing, diversity and leadership development by establishing a community of leaders and empowering colleagues to lead strategic initiatives. I am particularly proud of my sponsorship of the Black Professionals Network which helps create an environment where colleagues can thrive and bring their whole selves to work.

How do you use AI within your legal team to improve efficiency while maintaining quality, governance and integrity? How do you think AI will impact in-house legal functions more widely?

AI presents one of the biggest opportunities for the legal profession in a generation. Within our team, we view AI as a tool that augments expertise rather than replaces it. We have been exploring technologies that support contract management, drafting, review and risk analysis, allowing lawyers to spend more time on strategic advice and complex problem solving.

However, innovation must be balanced with responsible governance. We have established clear expectations around data protection, confidentiality, regulatory compliance and human oversight. Lawyers remain accountable for the advice provided, and AI-generated outputs are always subject to professional review and judgement.

I believe AI will transform legal functions by reducing administrative burdens, accelerating access to information and enabling teams to focus on higher-value strategic work. The organisations that succeed will be those that embrace innovation while maintaining strong ethical and governance frameworks.

The role of the GC has evolved significantly into that of a strategic business partner. How do you balance commercial objectives with legal risk?

GCs must understand not only the law, but also the commercial realities facing the business. My approach is to focus on enabling strategic outcomes rather than simply identifying risks.

In order to do this, I work closely with senior stakeholders from the earliest stages of decision-making, understanding the organisation’s objectives and helping shape practical solutions that achieve those objectives whilst remaining within acceptable risk tolerances. We continuously need to consider how risk can be managed effectively.

By fostering strong relationships across the business (which ensures they are engaged early on in projects), maintaining transparency and encouraging constructive challenge, legal teams can become trusted advisers who help drive growth, innovation and sustainable success.

What are the most important attributes of the modern GC and what advice would you give to those aspiring to be an in-house lawyer?

The best GCs combine legal expertise with commercial judgement, leadership and adaptability. They also look after, support and understand their people. Today’s business environment is increasingly complex, requiring leaders who can navigate legal uncertainty while inspiring teams and influencing across organisations.

For aspiring in-house lawyers, my advice would be to develop a genuine understanding of how businesses operate. Build relationships, stay curious and seek opportunities beyond traditional legal work. Experience in areas such as compliance, risk management and governance can provide valuable perspectives and help develop a broader leadership skillset.

Most importantly, remember that success is measured by the value you create for the organisation and the people around you. Technical excellence remains essential, but empathy, collaboration and integrity are what ultimately distinguish exceptional leaders.
