The National Trust manages historic properties and areas of countryside in England, Wales and Northern Ireland. In September 2020, the Trust commissioned a report on connections between their properties and colonialism, including links with historic slavery. The report attracted the attention of a group of Conservative MPs who attempted to discredit the work of the historians who produced it. In January 2021, we spoke with Professor Corinne Fowler of the University of Leicester about the work and the attacks on it.
