Virgin Media has urged the government to end the uncertainty about the UK's upcoming exit from the European Union (EU).
According to Chief Executive Tom Mockridge, the company's ability to get more broadband investment could be hit unless more details about how Brexit should occur are provided, the Register reports.
This, he said, is important because when Virgin Media has to make its next submission to parent company Liberty Global for investment in the UK and Ireland, it will be competing against colleagues from other territories, such as Romania and South America.
Speaking at the Broadband World Forum event, Mr Mockridge acknowledged that Prime Minister Theresa May has confirmed the government will invoke Article 50 by the end of March 2017.
However, he said the degree of uncertainty over Brexit remains high and the government needs to be "clear and forthright" about exactly what it will involve.
The company is currently spending £3 billion on its Project Lightning initiative, which will lead to 17 million homes and businesses in the UK having access to its ultrafast network by 2019.
Virgin Media has also been keen recently to talk up the quality of the UK's broadband infrastructure, amid ongoing criticism of BT's control of its infrastructure subsidiary Openreach.
Last month, Virgin Media published a joint advert with BT in national newspapers, which claimed that £15 billion has been invested in broadband technology over the last five years and that Britain boasts faster average download speeds than France, Germany, Spain and Italy.
"We don’t agree with the concept of stripping BT of its network," Mr Mockridge stated. "For investors and the public sector to take away a big piece of the company and put it somewhere else is a bad message. We don’t need the government knocking BT around."
