Dec. 3 (Bloomberg) -- U.K. prosecutors will not drop charges against Andrei Lugovoi for the radiation murder of Alexander Litvinenko following the former Russian intelligence agent's election as a member of parliament yesterday.

``As far as we are concerned this changes nothing,'' the British Embassy in Moscow said in a statement read by telephone today. ``Lugovoi remains wanted in the U.K. in connection with the murder of Alexander Litvinenko.''

Litvinenko, a critic of President Vladimir Putin who went into exile in London and became a British citizen, died last November after being poisoned with radioactive polonium-210. U.K. prosecutors asked Russia in May to extradite Lugovoi to face trial for the murder. Russia refused, citing a constitutional ban on extradition.

Lugovoi campaigned for the State Duma, the lower house of parliament, as the No. 2 in Vladimir Zhirinovsky's Liberal Democratic Party of Russia. The LDPR had 8.2 percent with 98 percent of the vote counted, ensuring it will clear the 7 percent barrier for representation in the Duma. Lawmakers enjoy legal immunity in Russia. Lugovoi is not required to take up his seat.

Putin's United Russia party swept the election, winning 64.1 percent with 98 percent of the vote counted.
