Britain's Crown Prosecution Service (CPS) says a man accused of making racist threats against investment manager and EU campaigner Gina Miller has been convicted.
Rhodri Philipps will be sentenced on July 13 after he was convicted on two counts of sending a menacing public communication, one relating to Miller and one about an immigrant on benefits who had featured in a news article.
Philipps was arrested in December on suspicion of making "racially aggravated malicious communications" against Miller, who took the British government to court over triggering formal talks on Britain's exit from the European Union.
She has received death threats and abuse since featuring prominently in media coverage of the case.
The CPS said Philipps had posted a comment on Facebook in November 2016 under the title Viscount St Davids, describing Miller as a "troublesome" first generation "immigrant boat jumper" and offered a STG5000 ($A8,414) bounty on her head.
