I'd never heard of him either but saw this online:
In 2015, he came third at the Jack Petchey 'Speak Out' challenge for his speech on the state of British education, urging the audience to "take off their ties and blazers and bring on the education revolution". Since then, he has gone on to do more public speaking events, frequenting the Highgate Literary and Scientific Institute at their quarterly debates: wowing the affluent North London audience with his "Churchillian" voice as he tackles topics like austerity, higher education and the NHS. Other speakers at the HLSI debates have included well-known public figures like the Spectator Columnist, Toby Young and Liberal Democrat Peer, Lynne Featherstone.
So he must be in demand with his "Churchillian" voice, unless he wrote that bit himself?
