Lord Nicholas Phillips of Worth Matravers is to become the new Lord Chief Justice of England and Wales.
He will take over the role from 1 October, replacing Lord Woolf following his planned retirement from the role at the end of September.
Lord Justice Anthony Clarke will subsequently take over Lord Phillips’ current role as Master of the Rolls, which Lord Phillips has held since June 2000.
Meanwhile, Lord Justice Igor Judge has been appointed to the newly-created role of president of the Queen's Bench Division.
Lord Woolf welcomed the new appointments, stating that he was sure the changes would enable the constitutional changes brought about by the Constitutional Reform Act 2005 to continue to be implemented smoothly.
