An Italian actress who promised to perform a sex act on everyone who voted no in her country's referendum has completed the first date of her tour.

Paola Saulino, 27, told fans that she was a 'woman of [her] word' after announcing tour dates in 10 Italian cities in December.

She posted a photograph of herself on Instagram on Saturday, along with the caption: 'First step of #pompatour is gone! A little bit tired [but] everthing is okay.'

The actress and glamour model added: 'This year is started in a best way as possible.'

Ms Saulino, whose Instagram page features a number of suggestive shots, has flown from her home in Los Angeles to begin the first leg of her Pompa Tour. 'Pompa' is an Italian slang word for oral sex.

She initially made the promise to perform a sex act on everyone who voted no in Italy's referendum on November 23, before announcing tour dates in December.

Ms Saulino said she would be visiting Rome, Florence, Bologna, Verona, Milan, Turin, Naples, Bari, Lecce and Palermo this month for the first leg of her tour, urging people to fill in a booking form if they had voted No.

Some have dismissed the tour as a publicity stunt, with several Instagram users asking for 'evidence' that she had kept her promise.

However, others defended the actress and told critics to 'stay quiet' if they didn't know - adding that photographs were not permitted to be shared online.

Italy's Prime Minister Matteo Renzi had called a referendum on constitutional reforms, which became a vote on confidence in his government.

But the move backfired and he resigned shortly after exit polls in at the start of a December indicated a 'no vote'.
