Rutland and Melton MP Sir Alan Duncan (Con) was officially knighted by the Prince of Wales during an investiture ceremony at Buckingham Palace on Friday.
Sir Alan was awarded the title of Knight Commander of the Order of St Michael and St George in the summer for services to International Development and UK/Middle East relations.
Fifty years ago, Sir Alan attended his father’s own investiture ceremony at the palace - Wing Commander James Duncan received an OBE for services to the Royal Air Force – and he was delighted to continue the tradition.
Alan said: “I am deeply honoured and proud to receive this knighthood. It has been an enormous privilege to have helped contribute to Britain’s relationship with countries around the world, but in particular the Middle East.
“To follow in my father’s footsteps by being recognised in this way is humbling and I am extremely grateful.”
