Turkey opposition calls for referendum to be annulled
Turkey's main opposition party has filed a formal request seeking the referendum to be annulled because of voting irregularities.
Bulent Tezcan, deputy chairman of the Republican People's Party, announced the move at the Ankara offices of the electoral board.
He said the results of the referendum on constitutional changes are "illegitimate" and the party would use all legal paths to challenge it.
Mr Tezcan said that "we demand the cancellation of this referendum".
