The UK's decision to leave the EU could have far-reaching implications for the nation's telecoms industry in the months ahead, with the matter of Brexit drawing into question the position of BT and that of a perceived monopoly from the firm's rivals.
Vodafone, Sky and TalkTalk have banded together in the wake of the EU referendum to contact the UK telecoms regulator Ofcom and call for the body to once more examine the ownership of BT's Openreach division.
Openreach is the engineering company responsible for the management of the UK's broadband network and BT's rivals believe this entity should be split from the telecoms provider in order to create a more level playing field for the sector as a whole.
Ofcom Chief Executive Sharon White is therefore now coming under increasing pressure to "do something bold", as the lobbyists claim that, freed from the oversight of Brussels, any decision on the future of BT that is made by the regulator would be binding.
Ms White opted against a forcible break-up of BT and Openreach in a review earlier this year, as the potential for European litigation due to the wider ramifications for other operators across the EU had proven extremely likely at the time. However, BT's rivals argue that with the UK now moving out of the EU, the potential legal fallout of such a move could be minimised.
Responding to the growing pressure, a spokesperson for BT told the Times: "Regulatory certainty is vital if companies are to invest and BT will continue to engage with Ofcom to try to find a constructive way forward. The Brexit vote changes nothing in that regard."
However, it remains to be seen whether or not the regulator will be convinced of this argument, especially as Vodafone Group is set to meet with Ofcom next week and is widely expected to use this meeting as an opportunity to push for a post-Brexit shift in the fundamental makeup of the UK telecoms industry.
