Yn ystod trafodaethau ar 1 Medi, rhannodd Llywodraeth y DU ar lafar rywfaint o’r dystiolaeth newydd hon. Er inni ofyn amdani sawl gwaith, ni chawsom y dystiolaeth newydd yn ysgrifenedig, tan neithiwr.
During discussions on 1 September, the UK Government verbally shared some of this new evidence.  Despite repeated requests, we were not sent the new evidence in writing, until last night.
