Heidi leads Global Justice Now’s pharmaceutical campaign to fight for access to medicines in the UK and across the world as well as the organisation's trade campaign. She has co-authored policy reports on the failings of the pharmaceutical innovation system and how it has left communities across the world without access to effective treatments. She has previously led and won the campaign to challenge the UK government's support for the New Alliance - an aid scheme that benefited corporations at the expense of Africa's small farmers. She has played an active role in the global movement for food sovereignty and in the development of the People's Food Policy. She has also campaigned on a range of economic justice issues such as food speculation, Europe’s bilateral trade deals, the World Trade Organisation and stopping RBS’s unethical investments.
