It seems as though none of the big players want to upset the apple cart and declare their position on Brexit. This is understandable seen as it's a subject that their consumers are almost exactly divided on, with strong opinions on both sides of the exchange. 

One of the main arguments from the leave camp is that there's too much EU intervention, diluting our sovereignty. From a B2B point of view, it can be argued that EU regulation has positively affected the industry. Two key contributions spring to mind immediately; the reduced roaming costs for mobile users travelling abroad in Europe, and the collective 5G infrastructure improvement plans that are on the horizon. It'll be interesting to see whether such positive improvements will remain in place and continue to be developed over the coming months and years.
