Havel was re-elected president in 1998. He had to undergo a colostomy in Innsbruck when his colon ruptured while he was on holiday in Austria. On 30 January 2003, Havel signed "The letter of the eight". Havel left office after his second term as Czech president ended on 2 February 2003. Václav Klaus, one of his greatest political adversaries, was elected his successor as president on 28 February 2003. Margaret Thatcher wrote of the two men in her foreign policy treatise "Statecraft", reserving the greater respect for Havel. Havel's dedication to democracy and his steadfast opposition to the Communist ideology earned him admiration.
