In the July 2918 Taxcast: a firewall to protect EU citizens from the Big Four accountancy firms and the tax avoidance lobby. Plus, we discuss UN Rapporteur on Poverty and Human Rights Professor Philip Alston's announced visit to the UK to look at austerity and the human rights consequences: his report on the US was hard-hitting and controversial. What will he make of the UK? Also, we look at Transparify's 2018 think tank funding transparency rankings and talk about how opacity is the name of the game for many of the 'free market' lobby groups pushing for Brexit, deregulation, privatisation and tax havenry, such as the Institute for Economic Affairs.
