The head of Britain’s Environment Agency (EA) has resigned after being heavily criticized for not cutting his Christmas holiday in Barbados short to return home to lead the response to floods last month. Required to work a three-day week for £100,000 (US$142,992) a year, Sir Philip Dilley said he quit because of the “inappropriate” expectation for him, as a part-time chairman of the EA, “to be available at short notice throughout the year”.
