London - Russian lesbian pop act Tatu and legions of schoolgirl fans have fallen foul of London police who cited ancient parliamentary laws to ban a video shoot outside the Houses of Parliament.

The fans, dressed in school uniforms and knee-high socks, turned up for filming on Albert Embankment, opposite the Houses of Parliament, but police had already told producers to move on.

"The Sessional Order states that persons cannot gather near the House of Commons or House of Lords when parliament is sitting," a police spokesman said.

Tatu shot to fame in Britain in February with their debut British single "All the Things She Said", the video of which featured a controversial lesbian kiss -- branded "paedo-pop" by critics.

Music websites said the teenage pop stars, Julia Volkova and Lena Katina, were later joined by around 300 girls and were filming the video for "Show Me Love" outside the Tate Modern art gallery on the south bank of London's River Thames.
