OUKTP-UK-FINANCIALThe French can never resist blaming a strong currency for their misfortunes. So it should come as no surprise that Henri Guaino, President Nicolas Sarkozy’s influential political adviser, has said that having the euro at $1.50 is “a disaster for European industry and the economy”. Since the euro stood at just above $1.49 as he spoke on Tuesday, Guaino presumably sees the single currency area as on the edge of the abyss.
