The Soros-backed Best for Britain group working to overthrow the government and block Brexit is “undemocratic”  according to  founder Gina Miller .
 Miller  became well-known as an opponent of Brexit after using the Supreme Court to force the Government to seek Parliament’s approval to activate Article 50 of the Lisbon Treaty and kick off the Brexit process  which could have seen MPs vote down the will of the people.
The group is working to build a network of powerful allies to undermine the Government before it can implement the Brexit vote  and  Miller  is insisting the public has the “right to know” who is backing it as it fights the referendum result.
In her statement   Miller  slammed the lack of “transparency about key players’ motivations  agendas and activities”  and urged “those keen to play their part in the Brexit debate to be open and honest about what they stand for  whom they represent and by whom they are funded”.
