Lalith was active in all the protests. But he was also the first person from the Third World I got to know well and so helped shape my attitudes there too. Peaceful in everything he did, he was nevertheless quietly forceful in a characteristically Buddhist way. Reading law, he was determined on a career at the Oxford Union, like several other distinguished Sri Lankans before him. In a generation which included such notable debaters as Brian Walden, Peter Brooke and Tony Newton, he was successively secretary, treasurer and librarian and became president in Hilary Term 1958 - the first Jesus president since the end of the Second World War. I recall in particular a debate in which he and an invited Bryan Magee took on another invited guest, Oswald Mosley - a debate which seems more resonant now given the fact that racial bigotry eventually ended Lalith's life.
He never made any bones about the fact that his colour helped his political career at Oxford, since he could always play the role of the token black.
