Russian duo Tatu have been threatened with disqualification from the Eurovision Song Contest after they tried to skip rehearsals for Saturday night's show.

Flame-haired singer Julia Volkova refused to continue yesterday's on-stage practice in Riga, complaining of a sore throat.

The producers of the show said that Tatu, who are favourites to win, would be disqualified unless they continued with the rehearsal.

They eventually returned to the stage and completed their song.

Ireland will be represented by Mickey Harte, singing 'We've Got The World Tonight', on Saturday 24 May.
