United Group plans to invest 2.0 billion euros ($2 billion) in Greece up to 2027 to upgrade its telecoms infrastructure, the prime minister's office said on Thursday, Reuters reports.

United Group, majority owned by private equity firm BC Partners, will install a 10-gigabit fiber optics network to service 4.5 million customers, the office of Prime Minister Kyriakos Mitsotakis said in a statement.

The conservative government views the deal as a stepping stone towards the digitalization of public services, one of its key priorities.

Mitsotakis, who met with United Group representatives on Thursday in Athens, said he expected 2022 would be "a record year for Greece in terms of attracting foreign investment."

"Your decision is proof of the confidence shown by both domestic and international investors in Greece's prospects," he said during the meeting.

United Group CEO Victoriya Boklag said the company was seeking a long-term relationship with Greece.
