Our guest on the latest episode of the J-Lab podcast is Martina Lees, a senior writer for the Sunday Times. Next month sees the sixth anniversary of the Grenfell Tower disaster, when fire destroyed a 23-storey tower block in West London, killing 72 people. Martina has spent much of the last few years seeking answers to why the disaster really happened, and who was to blame. She recently won a British Journalism Award for holding to account those responsible for the biggest public housing scandal in 50 years, and for campaigning to free millions of people from having to pay for dangerous cladding to be replaced. In our conversation, Martina explains why she became a journalist, what interested her in reporting this particular story, how she turned her reporting into an impactful campaign and how to ask the questions that no-one else is asking. J-Lab is a podcast by the Civic Journalism Lab at Newcastle University.
