Fine Gael MEP Mairead McGuinness has been re-elected Vice President of the European Parliament after topping the poll.
There was applause for the Midlands-North West MEP as she was elected in the first round, polling 466 votes out of the 618 valid votes cast or 75% of MEPs.
She was well ahead of the absolute majority of 310 votes required and 88 votes ahead of the next elected Vice President.
Having topped the poll, Ms McGuinness will be First Vice-President of 14 Vice-Presidents in the parliament.
Afterwards she said she was delighted with the result.
"I am honoured to have been re-elected as Vice-President of Parliament and as First Vice-President in particular with such strong support from across the House, reflecting my work as a fair and firm Vice-President," said Ms McGuinness.
She previously served as Second Vice-President of the parliament.
Minister for Foreign Affairs Charlie Flanagan said: "It is important and useful to have an Irish MEP in this prestigious position, and I'm sure that she will work very effectively with the new European Parliament President, her EPP colleague, Antonio Tajani."
Last month Ms McGuinness lost out in her bid to secure the European People's Party nomination for the race to become president of the European Parliament.
She was defeated for the nomination by Italian Mr Tajani, who yesterday was elected the new president of the European Parliament after a final round of voting.
