The second day of the inaugural meeting of Dublin Citizens' Assembly has heard addresses from the chief executives of the four Dublin city and county councils.

Sixty-seven citizens and 12 councillors from Dublin's four local authorities gathered in Malahide to consider what type of directly-elected mayor would best serve the capital.

The Government has committed to creating the office, and it is expected Dubliners will be asked to elect a mayor in 2024.

Yesterday, the Assembly's chairman, former Dublin Football Manager Jim Gavin said its work would influence the city's future for generations.

This morning, Chief Executive of Dublin City Council Owen Keegan said he would like Dublin to keep the four local councils but it is up to the Citizens' Assembly to decide what structures would work best with a directly-elected mayor.

Chief Executive of Fingal County Council AnnMarie Farrelly said her local authority has a bigger population than Limerick city and council which is to get its own directly-elected mayor, and questioned whether it would be in the best interests of Fingal to have it "subsumed" under one directly-elected mayor for the whole city and council.

Chief Executive of South Dublin County Council Daniel McLoughlin said the assembly should concentrate on what the mayor should do and the structures would follow from that.

Chief Executive of Dún Laoghaire-Rathdown County Council Frank Curran said the officials will work with whatever structures are decided.

Asked what powers they would like to see transferred from central government to local authorities, Mr McLoughlin and Mr Curran said they would like to see more local control over health and education services.

The relationship between local authority chief executives and elected representatives was a topic that was raised even before the four top officials of Dublin's four councils had their session with the Citizens' Assembly.

This morning, citizens asked the expert panel of academics why chief executives sometimes overrule councillors despite their democratic mandate.

Dr Aodh Quinlivan said it does not happen very often but Councillor Lorraine Hall from Dún Laoghaire-Rathdown gave an example of how the Minister for Housing overruled a planning decision by councillors in her area.

Councillor John Walsh from Fingal said in his experience the issue was that it was more often central government overruling local officials and councillors.

Dublin Citizens' Assembly concluded its first weekend session at lunchtime today and will meet over another two weekends.

It may meet again after the summer but must finish its work and report back to the Oireachtas within nine months.

A national Citizens' Assembly on Biodiversity Loss will meet for the first time at Dublin Castle in two weeks' time.
