Dublin City Council has apologised for issuing the wrong polling cards to 35,000 voters in the capital ahead of the referendum on Friday.

The City Council says it has now taken immediate action to rectify the error.

As many as 9,000 people have been sent the incorrect information about their polling station, while people who are new voters have not received any cards at all.

And a small number of cards have been issued to people who are now deceased.

Dublin City Council says every effort is now being made to get the correct information out to those effected before Friday.

Letters have now been sent to voters whose original polling cards directed them to the wrong polling station, advising them of the correct location to cast their vote.

Letters are also going to voters who are new to the Electoral Register and/or who have changed address recently.

In the meantime the Council is reminding voters that they are not required to present a polling card at their polling station in order to vote in the referendums.

It says that valid ID such as a passport, driver's licence or a garda identity card should be brought when going to vote.

Dublin City Council says an IT systems error resulted in inaccurate information appearing on a number of the polling card.
