LONDON, June 13 -- The British Foreign Office said Tuesday Queen Elizabeth had approved the award of an honorary knighthood to former U. S. Secretary of State Henry Kissinger. Kissinger will be appointed an Honorary Knight Commander in the Most Distinguished Order of Saint Michael and Saint George.

Kissinger will be able to use the initials KCMG after his name but, because he is not one of Queen Elizabeth's subjects, he cannot be referred to as Sir Henry Kissinger. The honor was in recognition of Kissinger's contribution to Anglo- American relations. The queen will present the award to him at Buckingham Palace on June 20, a Foreign Office spokesman said. 'It's for his long-term committment to Anglo-American relations and we felt he should be honored for his contribution,' the spokesman said. Other U.S. citizens who have recently received honorary knighthoods include former Secretary of State Cyrus Vance, former gens. Norman Schwarzkopf and Colin Powell and former House Speaker Tom Foley.
