RTÉ.ie/lisbon has complete coverage of the Lisbon Treaty

Polls have closed in the vote on the European Union's new Lisbon Treaty.

Counting begins at 9am tomorrow morning and results should be announced by early evening.

Turn-out is estimated to be at around 40%.

Opinion polls have indicated that the result is too close to call, despite an all-out campaign by both sides.

Voting was reported to be fairly slow in many areas.

Reports also suggest that voting was heavier in urban than in rural areas.

It also appears that turnout was higher in middle class than in working class districts, which would be in line with normal election and referendum patterns.

Polling stations around the country opened at 7am this morning and closed at 10pm.

Among the early voters was President Mary McAleese, who cast her ballot at St Mary's Hospital in the Phoenix Park.

Taoiseach Brian Cowen was also out early in his home town of Tullamore, while Fine Gael leader Enda Kenny cast his ballot in Castlebar.

Labour Party leader Eamon Gilmore voted in Shankill in Dublin, while Environment Minister and Green Party leader John Gormley voted in Ringsend.

Ciaran Cannon of the Progressive Democrats cast his vote this morning at St Joseph's school in Carrabane, Co Galway

Leading figures in the No campaign were also voting early: Declan Ganley, the chairman of Libertas, voted in Tuam, Co Galway; Patricia McKenna, the former MEP who is chairperson of the People's Movement, voted in Drumcondra in Dublin; while Sinn Féin MEP Mary Lou McDonald, who fronted her party's anti-Lisbon campaign, was in Castleknock.

Problems at Monkstown polling station

In Dublin, up to 30 people from a nursing home and sheltered housing scheme in Monkstown were unable to vote because there was no wheelchair access ramp available at their polling station.

The problem arose at the Knox Hall polling station in Monkstown.

A group of older people from the Cheshire Ireland Centre went to vote, but were unable to enter the hall because they were using wheelchairs or were unable to climb steps.

The residents say they were not told in advance that the hall was not wheelchair accessible, and it did not say this on their polling cards.

The Returning Officer for the area, John Fitzpatrick, said an examination was carried out at the polling station in advance of polling day to see if it was accessible for disabled people.

He said it was decided that although Knox Hall was not wheelchair accessible, it would not be safe to use a temporary ramp in that particular location.

He said advertisements were put in two national and a number of local papers to this effect advising people that they should contact their Returning Officer to arrange to be transferred to another polling station or to have their vote collected at home.

He said this was the correct procedure under the relevant legislation.

Greek parliament ratifies Treaty

The Greek parliament approved the treaty by 250 votes to 42 late last night.

The ruling New Democracy conservatives and main opposition Pasok socialists both supported the measure.

The opposition KKE Communists, Syriza leftists and the small nationalist party LAOS voted against the treaty, demanding that it be put to a referendum.

Leftwing demonstrations were held against the treaty in Athens and the northern city of Salonika.

The parliaments of Estonia and Finland had both overwhelmingly approved the treaty earlier in the day.
