English: I raise to speak with a heavy heart on behalf of the Labour group. First, I'd like to extend all of our condolences to Steffan's wife, Shona, his son, Celyn, and the rest of his family and friends. Steffan was so widely respected by Members of all parties across this Chamber and held in really great esteem. His razor-sharp intellect was clear to see, as was his grasp of the key issues and his genuine passion to make Wales a better place. And in the work that he did on first proposing the EU continuity Bill, and his work thereafter on 'Securing Wales' Future', he will undoubtedly leave a strong legacy here in Wales. I'd also like to say a few points personally as well, because I arrived in this Chamber in May 2016, at exactly the same time as Steffan, and I was struck very quickly by how non-partisan a place this Chamber is. It was actually Steffan who played a key role in first showing me that, as we both served on BIPA together - the British-Irish Parliamentary Assembly. I remember meeting with him and the other representatives prior to our first trip and feeling somewhat trepidatious about how I would get on with Members of other parties during that trip. But Steffan actually jumped over the security barriers in Tŷ Hywel, such was his enthusiasm for the work we were about to undergo, and that certainly did break down any barriers that there were. From then on, I found that there was nothing that he could not talk about and show a huge amount of knowledge on, as other colleagues have said, from international examples to national and to local. The depth of knowledge and passion he had across all different areas of politics was really quite incredible. But virtually every conversation that I had with him would always come back to his family, and that was something that really struck me. He was, clearly, very much a family man, a very proud father, and spoke with great affection of his wife and his parents too, and how they had shaped his politics. His talent will undoubtedly be a great loss to the party, Plaid Cymru, and a great loss to Wales as a nation as well, but of course, more importantly, a loss that is felt by his family and his friends too. Like Steffan, I too am a historian at heart, and I am confident that, when the history of this fifth Assembly is written and this chapter of the history of Plaid Cymru, Steffan's role will be a shining light.
Welsh: Rwy'n codi i siarad gyda chalon drom ar ran y grŵp Llafur. Yn gyntaf, hoffwn fynegi ein cydymdeimlad ni i gyd â gwraig Steffan, Shona, ei fab, Celyn, a'i holl deulu a'i ffrindiau. Roedd Steffan mor fawr ei barch yng ngolwg Aelodau o bob plaid ar draws y Siambr hon ac roedd llawer o edmygedd ohono. Roedd ei ddeallusrwydd craff yn glir, fel yr oedd ei afael ar y materion allweddol a'i angerdd gwirioneddol i wella cyflwr Cymru. Ac yn y gwaith a wnaeth, yn gyntaf ar gynnig Bil parhad UE, a'i waith ar 'Ddiogelu dyfodol Cymru' wedi hynny, bydd yn sicr o adael etifeddiaeth rymus yma yng Nghymru. Hoffwn sôn hefyd am ychydig o bwyntiau personol, gan i mi gyrraedd yn y Siambr hon ym mis Mai 2016, yr un pryd yn union â Steffan, ac fe'm trawyd i'n gyflym iawn pa mor amhleidiol mewn gwirionedd yw natur y Siambr hon hefyd. Steffan wnaeth chwarae'r rhan allweddol wrth dangos hyn i mi yn y lle cyntaf, gan fod y ddau ohonom ni'n gwasanaethu ar BIPA gyda'n gilydd - y Cynulliad Seneddol Prydeinig-Gwyddelig. Rwy'n cofio cyfarfod gydag ef a chynrychiolwyr eraill cyn ein taith gyntaf a theimlo braidd yn anniddig o ran sut y byddwn yn gallu dod ymlaen gydag Aelodau o bleidiau eraill yn ystod y daith honno. Ond neidiodd Steffan dros ben y rhwystrau diogelwch yn Nhŷ Hywel, cymaint oedd ei frwdfrydedd am y gwaith yr oeddem ni ar fin ei wneud, ac yn sicr fe chwalwyd unrhyw rwystrau a oedd yn bodoli. O hynny ymlaen, fe ddysgais nad oedd dim na allai ef ei drafod a dangos gwybodaeth eang iawn amdano, fel y soniodd yr Aelodau eraill, yn enghreifftiau rhyngwladol, cenedlaethol a lleol. Roedd dyfnder yr wybodaeth a feddai arno ym mhob maes o wleidyddiaeth a'i angerdd yn gwbl ryfeddol. Ond byddai bron pob sgwrs a gefais gydag ef yn troi'n ôl bob amser at ei deulu, ac roedd hynny'n rhywbeth a wnaeth argraff wirioneddol arnaf i. Roedd yn amlwg yn ddyn teulu i raddau helaeth iawn, yn dad balch iawn, a siaradai'n annwyl iawn am ei wraig a'i rieni hefyd, a sut yr oedden nhw wedi dylanwadu ar ei wleidyddiaeth. Bydd ei dalent, yn ddi-os, yn golled enfawr i'w blaid, Plaid Cymru, ac yn golled enfawr i genedl y Cymry hefyd, ond wrth gwrs, yn bwysicach, yn golled i'w deulu a'i gyfeillion. Fel Steffan, rwyf innau hefyd yn hanesydd yn y bôn, ac rwy'n hyderus, pan gaiff hanes y pumed Cynulliad hwn ei ysgrifennu a'r bennod hon yn hanes Plaid Cymru, bydd gwaith Steffan yn llusern olau.
