Holyhead marina opponents take petition to Cardiff Bay

The outline proposals were accepted by councillors on Anglesey at a meeting last month

Campaigners against plans for a new £100m marina in Holyhead are travelling to Cardiff Bay to hand over a petition.

The petition, with 4,500 signatures and several hundred letters of protest, will be handed to planning inspectors at the Senedd on Tuesday.

The group opposes plans which include a new 500-berth marina, 326 homes, a hotel and business units.

Opponents have said the marina would destroy Newry beach but developers say it will create 700 jobs.

The outline proposals were accepted by councillors on Anglesey at a meeting last month.

Protesters packed the public gallery of the council chamber in Llangefni.

The plans, put forward as a joint venture between Stena Line and the Conygar Investment Company, were voted through with seven votes in favour and none against.

The scheme includes a new youth centre, a public beach area and a new maritime museum and visitor centre.

Those in favour say Holyhead needs to reinvent itself and create a future for its young people.
