Portugal’s Economy Minister has resigned after making an offensive gesture in parliament at a political opponent.Manuel Pinho represented two horns, which means calling someone a cuckold. Amid outrage in the house, Prime Minister Jose Socrates apologised in the name of the government. He said that nothing could justify the minister’s actions. The controversy surrounding Pinho is the last thing the ruling Socialists need. Having taken a beating in last month’s European elections, they are gearing up for a general election in September. Amid rising unemployment in Portugal, the government has faced heavy criticism over its handling of the economic crisis.
