Dyna pam y mae'r Prif Weinidog wedi ysgrifennu heddiw ar y cyd â Phrif Weinidog yr Alban yn galw ar Brif Weinidog y DU i ofyn am estyniad i'r cyfnod pontio er mwyn darparu’r hoe angenrheidiol i gwblhau'r trafodaethau. Mae hyn yn adlewyrchu’r  alwad a wnaed gan y Prif Weinidog ar ddechrau'r argyfwng hwn, dros 11 wythnos yn ôl i'r Prif Weinidog geisio estyniad er mwyn caniatáu i’r holl lywodraethau ganolbwyntio'u sylw llawn ar ymladd y pandemig - cais a anwybyddwyd.
That is why the First Minister has today written jointly with the First Minister of Scotland calling on the Prime Minister to ask for an extension to the transition period in order to provide a breathing space necessary to complete the negotiations. This echoes the call made by the First Minister at the start of this crisis, over 11 weeks ago for the Prime Minister to seek an extension in order to allow all governments to focus their full attention on fighting the pandemic - a request which was ignored.
