I think in three cases specifically, we are a technology company, not a telecoms company and if we don't deliver that technology to our customers, they'll go to people that can. So my team, all of the teams in three, the teams and TCS, we are all looking to deliver the technology that we provide to our customers. Do they get the best experience of the applications. And the services that are overlaid onto those technologies, TCS are an important part of the security team and we think of them as a partner, You're part of our team that provides services to us. So whilst I have my direct team in the UK, the team that TCS provide support those functions and without them we simply wouldn't be able to do the job that we do in security. So I've only been at 3-4 two years now and I've worked with TCS all of that time. It's the first time that I have worked with TCS, but as I've already said, they are an integral part to the business. Of securing 3 in my opinion. And that partnership is quite important to me. I think it's the understanding that TC has TCS has of our technology. We don't have to explain why security is important, why certain things are more important than others. What does our threat landscape look like? TCS is understanding of all of that ahead of our conversations makes it much easier to concentrate on the important things to me as the CISO that I have to deliver. The partnership with TCS is successful because we don't have to keep explaining ourselves and. Our place in the UK market, TCS already understand that. I've only worked TCS for two years, and it's clear that collaboration prior to my arrival has set the foundations for a continued relationship, and that's important to me as CISO, because I often don't have time to continually explain why security matters are important to me, TCS's background and understanding make it easier for me to collaborate with them. I hope to continue the collaborative nature of the engagement over new projects. Obviously, we'll engage with partners that suit our needs the best.
