British police have arrested a man in connection with threats made to Gina Miller, the businesswoman spearheading the Brexit legal challenge in the UK.

The 55-year-old was arrested in Swindon on suspicion of racially aggravated malicious communications. He was later released on bail.

Officers launched an investigation over online threats made to Ms Miller since November 3rd.

The 51-year-old said on Monday that she had received a series of racist messages following her decision to lead a legal challenge against the British government.

She recently revealed she had spent stg£60,000 (€70,221) on security and told BBC Radio Five Live she was "apparently the most-hated woman in Britain".

Ms Miller, an investment manager and philanthropist, has become the figurehead of the legal challenge which argues Prime Minister Theresa May should not be able to trigger Article 50 to begin Brexit proceedings without a vote by MPs.

On November 3rd, the UK High Court ruled in favour of Mrs Miller and the case has been referred to the Supreme Court.

The country's top judges are currently hearing arguments from both sides and a final decision is expected in January.

Police also said that as a part of the same investigation they have issued a cease and desist notice to a 38-year-old man from Fife.
