Sinn Féin Senator Lynn Boylan has strongly indicated she will put her name forward for selection at a party convention this week to choose a candidate for the Dublin Bay South by-election.

Speaking in Leinster House, she said the candidate would be picked by the party members in the constituency.

The former MEP said the by-election would be a referendum on the Government's housing policy.

The by-election, which was triggered by the resignation of Fine Gael TD Eoghan Murphy, is expected to take place in early July.

It is thought that consideration is being given to either Wednesday 7 July or Thursday 8 July to hold the poll.

There is a view in Government that a midweek vote would lead to a larger turnout given the time of year when many people begin their holidays at weekends.

However, the writ has not been moved yet in the Dáil to formally set the election campaign in motion.

Several candidates have already been selected including James Geoghegan for Fine Gael, Labour's Ivana Bacik and Deirdre Conroy for Fianna Fáil, People Before Profit's Brigid Purcell, while Independent Mannix Flynn is also running.
