New names have joined the list of verified candidates for this year’s municipal elections. Robert Cappucci, of East Boston, has been approved for a spot on the ballot for mayor, joining City Councillor Tito Jackson and East Boston resident Joseph Wiley in challenging incumbent Mayor Martin Walsh.

A preliminary election will take place on Sept. 26 for the mayor’s seat, as well as for city councillor in districts one, two, seven, and nine.

Eight candidates are vying for the at-large city council seat, just shy of the number needed for a preliminary election in September. City Councillors Annissa Essaibi-George, Michael Flaherty, Ayanna Pressley, and Michelle Wu will face candidates Althea Garrison and William King of Dorchester, Pat Payaso of Roxbury, and Domingos DaRosa of Hyde Park.

In District Seven, there are now 13 candidates seeking the seat that will be vacated by Councillor Jackson. Former state Rep. Carlos Henriquez joined the ballot this week.
