“Rydw i wedi dweud yn glir beth sydd ei angen arnom ni o ran Brexit. Yn y lle cyntaf, mae angen i ni barhau i gael mynediad llawn a dirwystr at y Farchnad Sengl. Mae Cymru wedi denu buddsoddiad gan gannoedd o gwmnïau rhyngwladol ar sail mynediad at y farchnad sengl. Byddai methu â chynnal mynediad llawn, heb unrhyw dariffau na rhwystrau eraill rhag masnach, ar ôl gadael yr Undeb Ewropeaidd yn golygu ei bod yn anoddach denu buddsoddiad yn y dyfodol.
“I have been very clear about what we need from Brexit. First and foremost, we need continued full and unfettered access to the European single market. Wales has attracted investment from hundreds of international companies on the basis of access to the single market. Failure to maintain full access, free of tariffs and non-tariff barriers to trade post-Brexit could make sustaining and securing investment more difficult.
