Rydym wedi galw’n daer ar Lywodraeth y Deyrnas Unedig dro ar ôl tro i fuddsoddi rhagor mewn seilwaith er mwyn hybu twf ac amddiffyn swyddi. Dyma golli cyfle arall. Er bod yr economi yn tyfu o’r diwedd, dyma’r adferiad mwyaf araf ers cyn cof. Dywedodd y Swyddfa Cyfrifoldeb Cyllidebol ei hun mai bach iawn fydd effaith cyhoeddiad y Gyllideb heddiw ar dwf CMC blynyddol. Er bod y Gyllideb yn dangos bod yr economi a chyllid cyhoeddus wedi gwella, mae’r economi yn wannach o lawer na’r hyn yr oedd Llywodraeth y Deyrnas Unedig yn ei ddisgwyl pan lansiodd ei chynllun o arbedion ariannol ym mis Mehefin 2010. Roedd y Gyllideb hon yn gyfle i fuddsoddi rhagor o arian cyfalaf er mwyn gallu parhau i fuddsoddi mewn twf a swyddi. Nid yw Llywodraeth y DU wedi achub y cyfle hwn heddiw.
We have repeatedly called on the UK Government to increase infrastructure investment in order to boost growth and protect jobs.  This is another missed opportunity. Although the economy is at last growing, this remains the most sluggish recovery in living memory. The Office for Budget Responsibility has itself said that today’s Budget announcements will have a negligible effect on annual GDP growth. While the Budget shows that the economy and public finances have improved, the economy is much weaker than the UK Government expected when it launched its fiscal austerity plan in June 2010. This Budget provided an opportunity to boost capital investment to support continued investment to boost jobs and growth. The UK Government has not taken this opportunity today.
