An Indian-origin campaigner, who had mounted a successful legal challenge to prevent British Prime Minister Theresa May from triggering Brexit without Parliament`s approval, has spoken out of fears that she may be the target of an acid attack on the streets of London.Gina Miller, who has been targeted by Brexiters on social media for her stance against Britain`s exit from the European Union (EU), said she could be forced to leave Britain as a result of death threats and abuse against her. Miller, born Gina Nadira Singh in British Guiana (now Guyana) to Guyana`s former Attorney General Doodnauth Singh, has been a vocal campaigner as part of a "Best for Britain" drive. She lives under 24-hour security with her husband and three children, who she claims spend their weekends indoors due to fear. She said she would have to seriously consider leaving the UK. Scotland Yard has served eight cease and desist notices to people who had sent Miller threatening messages. Miller`s concerns of an acid attack come against the backdrop of a growing number of such crimes on the streets of London.
