Who are the seven people bidding to be the next president of Ireland?
On 27 October more than three million people will be eligible to vote for the ninth president of Ireland.
The president, who serves as head of state, is elected for a seven-year term and can be re-elected only once.
The role itself is largely ceremonial but the president has the right, after consulting with the Council of State, to refer the constitutionality of bills to the Supreme Court and may also refuse the dissolution of the Dail to a Taoiseach who has lost a vote of confidence.
Everything else the president does must be approved by the government of the day.
So who are the candidates in the running to become the next Irish president and take office on 11 November?
