Contact Hamish

Hamish is committed to fighting for justice and holding the state — including governments, the police and public bodies — to account.

After being called to the bar in 2018, Hamish spent two years as part of the legal team representing bereaved, survivors and residents in the Grenfell Tower Inquiry. He joined Nexus Chambers following the successful completion of his pupillage and has quickly built a formidable practice in criminal and public law.

Before coming to the law, Hamish had a successful career in politics, working as a senior advisor in the House of Commons and subsequently being elected himself as a local councillor. This experience makes Hamish well-suited to cases requiring an understanding of national and local governmental policies and processes.
