Who funds the Taxpayers Alliance?

Very interesting legal case just recently - the Taxpayers Alliance admitted that in describing one of its former employees as a "Walter Mitty fantasist", "so-called whistleblower" and "complete liar" for the crime of, wait for it.... divulging their illegal overspending by the Vote Leave campaign during the Brexit referendum.

Main points are:

They admitted to wrongful dismissal, unfair dismissal, direct discrimination and dismissal by reason of a philosophical belief in the sanctity of British democracy of the whistleblower

They co-ordinated with 9 other right-wing lobby groups that all occupy the same building. These include the Global Warming Policy Foundation, Vote Leave, Business for Britain (another right-wing pro-Brexit group), The European Foundation (ditto), Global Vision (ditto), Leave Means Leave (ditto), the Adam Smith Institute, the Institute of Economic Affairs and the Centre for Policy Studies. These organisations are often quoted in the mainstream media as 'think tanks' and presented as disparate groups, yet they all seem very closely linked; one could almost say they are different names for the same group, giving the misleading impression that they present a broad variety of right wing opinion in the UK, rather than the views of a small number of influential, wealthy individuals

The Taxpayers Alliance acted in concert with 10 Downing Street to smear the whistleblower

By conceding all the whistleblower's allegations, they avoided having to disclose details of their funders in court. The whistleblower's barrister said "“It is incredibly unusual for a respondent to make a complete concession on liability as the respondent has here. To wave a white flag to avoid disclosing documents and giving evidence in court is really unusual. They conceded everything.". This begs the question of who does fund them if it's so important not to disclose this information. We can be fairly certain it's not people who pay very much tax, I think.
