The engagement was not without controversy: Philip had no financial standing, was foreign-born (though a British subject who had served in the Royal Navy throughout the Second World War), and had sisters who had married German noblemen with Nazi links. Marion Crawford wrote, "Some of the King's advisors did not think him good enough for her. He was a prince without a home or kingdom. Some of the papers played long and loud tunes on the string of Philip's foreign origin." Elizabeth's mother was reported, in later biographies, to have opposed the union initially, even dubbing Philip "The Hun". In later life, however, she told biographer Tim Heald that Philip was "an English gentleman".
