On January 20 Washington officially asked Prague to accept a radar station as part of its anti-ballistic missile shield and Warsaw to agree to take anti-missile interceptors.

"The decision-making power is entirely in the hands of the parliamentarians," Defence Minister Vlasta Parkanova told the joint session.

An agreement needs the consent of two thirds of the two houses of the Czech parliament and is far from certain in view of the vigorous reaction to the US request.

Meanwhile the Czech government is preparing its official response to the United States, probably backing the opening of talks, Topolanek said.

They will last until the end of the year and if they end in an agreement with the United States building work on the radar station will begin in 2008 to 2010 and the first tests will be conducted in 2011-12, he said.

In the talks Prague will not follow Warsaw's reported example and ask for Patriot anti-missile missiles to protect its territory, Czech media reported.

"We shall not ask for Patriots," Deputy Foreign Minister Tomas Pojar said, according to CTK.

But Topolanek, questioned by the agency, did not rule out including the issue in the talks. The Russian foreign ministry said recently that deployment of elements of the shield in the Czech Republic and Poland would be a "mistake" and would have "negative consequences for international security".
