us secretary of state john kerry has been given the legion d'honneur, france's highest honour at a ceremony in paris on saturday. kerry's mother and aunt were born in paris in the early 1920s and america's top diplomat spent holidays as a young man at the family residense in saint-brignac-sur-mer, in brittany. kerry's french heritage and fondness for the country saw him attacked on the presidential campaign trail in 2004, when he was the democratic candidate running against republican george w bush. tensions were running high between paris and washington over the iraq war, to the extent that america's beloved junk food, french fries, were briefly renamed freedom fries, french foreign minister jean-marc ayrault said at the ceremony. a visibly moved kerry said france was america's "oldest ally". "long live french fries! long live france! long live the usa!" kerry said in french.
