STOCKHOLM, Sweden – Swedes have bombarded lawmakers with more than 1 million e-mails protesting the country's new eavesdropping law, adding to the growing public outcry over the measure, an official said Monday.

The contentious bill allows officials to eavesdrop on all cross-border e-mail and telephone traffic. The government plans to implement it in January.

The bill was passed June 18 in a 142-138 vote despite nationwide protests that are still continuing.

Critics say the law will encroach on privacy and jeopardize civil liberties. Supporters claim it is needed to fight international crime and terrorism.

Parliamentary spokeswoman Christina Green said protesters had sent 1.1 million e-mails to lawmakers by Monday afternoon, after the Expressen tabloid on Sunday launched an online campaign against the law.

The youth wings of the governing coalition parties oppose the law. The main opposition Social Democratic Party leader Mona Sahlin said she would move to annul it if her party returns to power in the 2010 election.

The lack of support for the legislation is a setback for Sweden's center-right government, which has seen its popularity decline in recent months.

The legislation gives Sweden's National Defense Radio Establishment the right to scan all phone calls, e-mails and faxes crossing Sweden's borders, without a court order.

Currently, e-mail and phone surveillance in the Nordic country of 9.1 million, known for openness and transparency, requires a court order if police suspect a crime.

However, the intelligence agency is allowed to spy on airborne signals, such as radio and satellite traffic without special permission.
