Dylan Williams' comments came on the day that Welsh Country Foods closed for the final time with the loss of 310 jobs.

He said that the island needed to see "major new investment if [they are] to recover those job numbers."
Production will cease today at a lamb processing plant on Anglesey with the loss of 310 jobs.
The future of the Welsh Country Foods site at Gaerwen was thrown into doubt in January, after supermarket chain Asda ended its order for lamb.
The union that represents workers at a lamb processing plant on Anglesey says that it is disappointed that a deal to save 310 jobs there has 'fallen through.'
In a statement, Unite said that the Gaerwen site will now close on Friday.
NFU Cymru told ITV News' Rob Shelley that the loss of the plant is a 'sad day for farmers' in north Wales.
The Welsh Government says that they are 'very disappointed' that the Welsh Country Food meat processing will close with the loss of 310 jobs.
In a statement, they said they had offered support to try and secure the sale of the site in Gaerwen on Anglesey.
NFU Cymru says news that the Welsh Country Foods meat processing plant on Anglesey is to close is a "body blow to lamb producers across Wales and to employment on the island of Anglesey and Gwynedd."
It said that it "means the last major slaughter facility in the north of Wales will close and lead to a large drop in overall slaughter capacity in Wales and a loss of levy income."
The owners of Welsh Country Foods say that they have explored 'every possible avenue' to prevent the loss of 310 jobs at the Anglesey plant.
In a statement the company said that it was an "extremely regrettable action but, unfortunately, we have been unable to identify any viable alternative to closure of the plant."
Vion Food Group, the owners of Welsh Country Foods, announced in January that it was planning to close the processing facility for Welsh lamb.
It blamed the decision of ASDA to 'de-list' Welsh Country Foods as a supplier.
At the time the company said that it would "explore every opportunity to limit any potential job losses."
They announced that they would begin a 90-day consultation with workers as they continued to work to attract new customers to the site.
The plant in Gaerwen previously handled 640,000 lambs every year.
