Sweden´s foreign minister has resigned following accusations she acted unconstitutionally. Laila Freivalds announced the news at a press conference with prime minister Goran Persson. She said: “Under the current circumstances I find it impossible to continue my work.”The controversy centres on the closure of a far-right website featuring cartoons of the Prophet Mohammed. It was shut down by a web hosting company after the foreign ministry contacted the firm. Freivalds claimed she did not know her officials had been in touch with the company, but documents later came to light showing she had been informed. Pressure on a business to close such a web site would be against the Swedish constitution. Freivalds was previously criticised because of the government’s perceived slow response to the Asian tsunami in which around 500 Swedes died.
