Britain's Electoral Commission said Tuesday it had fined the officially designated pro-Brexit campaign group £61,000 ($80,843) for breaching spending rules in the 2016 referendum and referred it to the police.

Two years since voting 51.9-48.1 to leave the EU, the United Kingdom, the political elite and business remain deeply divided over whether the country should leave the European Union on March 29, 2019, and if so how.

While opponents of Brexit have claimed the campaign to leave the EU cheated in the referendum, the Electoral Commission's chief executive Claire Bassett told BBC radio that its investigation was focused only on campaign spending violations.
