English: I only knew Steffan, like many others in this Chamber, since he was elected in 2016 to join us here, and in that short time, his decency and his intellect have made their mark on myself and many others, as we are hearing across the Chamber today. My colleague Jack Sargeant came into this Chamber with the thought of a kinder politics. Steffan embodied that kinder politics he wanted to do. He was decent, he was well thought of, he considered his arguments and he put forward a strong case, as has been highlighted already. Llywydd, Steffan's contribution to the Assembly has been recognised by all Members, but his contribution to the external affairs committee on which he sat was enormous. He brought to us the thoughtful consideration of the arguments and he put that thoughtful consideration not with an agenda of anything else other than the best for the people of Wales. That was his contribution. Now, we all know his political thinking and what was paramount to him was the existence of an independent Welsh national state. But more important to him was the actual improvement of the lives of people in Wales, and that's what he chose to achieve and work towards, and everything he did was for that. He brought to us cutting ideas, and scrutiny of Ministers, which sometimes they didn't enjoy either, because they were sometimes very wary of Steffan when he was in the committee because they knew what was coming. He went everywhere to try and get that information. I remember him telling me he went to London to go all round the embassies and the consulates to get information about what a future Europe would look like. I even remember him telling me that he was planning a trip to Norway with his family with the real intention of going to the Sweden-Norway border to see what went on on that border. Whilst we will miss his intellect and sharpness here in this Assembly, that is nothing compared to the loss that his family will be experiencing at this difficult time. My thoughts and prayers are with his family now and in the future, but one thing I do know is that his son will grow up to see his ambition realised at one point; I do believe that. Steffan's time might have been short, but his legacy will live on.
Welsh: Fel llawer o rai eraill yn y Siambr hon, dim ond ers iddo gael ei ethol yn 2016 i ymuno â ni yma yr oeddwn i'n adnabod Steffan, ac yn y cyfnod byr hwnnw, mae ei gwrteisi a'i ddeallusrwydd wedi gadael eu hôl arnaf i a llawer un arall, fel y clywn ni o bob rhan o'r Siambr heddiw. Daeth fy nghyd-Aelod Jack Sargeant i'r Siambr hon gyda'r syniad o wleidyddiaeth fwy caredig. Roedd Steffan yn ymgorfforiad o'r wleidyddiaeth fwy caredig honno yr oedd yn dymuno ei weld. Roedd yn gwrtais, roedd gan bobl feddwl uchel ohono, byddai'n ystyried ei ddadleuon a chyflwynai achos cryf, fel y nodwyd eisoes. Llywydd, mae cyfraniad Steffan i'r Cynulliad wedi cael ei gydnabod gan yr holl Aelodau, ond roedd ei gyfraniad i'r pwyllgor materion allanol yr oedd yn eistedd arno yn enfawr. Deuai ag ystyriaeth feddylgar i'r dadleuon ac fe ddefnyddiai'r ystyriaeth feddylgar honno gydag agenda am yr hyn a fyddai orau i bobl Cymru. Dyna oedd ei gyfraniad ef. Nawr, fe wyddom i gyd beth oedd ei safbwynt gwleidyddol a'r hyn a oedd o'r pwys mwyaf iddo ef, sef bodolaeth gwladwriaeth genedlaethol annibynnol i Gymru. Ond yn bwysicach yn ei olwg oedd gwelliant gwirioneddol ym mywydau pobl yng Nghymru, a dyna'r hyn a dewisodd ei gyflawni a gweithio ar ei gyfer, ac roedd popeth a wnâi i'r perwyl hwnnw. Daeth â syniadau trawsbynciol ger ein bron, a chraffu ar Weinidogion, nad oedden nhw'n ei fwynhau bob amser chwaith, oherwydd roedden nhw ddrwgdybus iawn o Steffan weithiau pan oedd ef yn y pwyllgor oherwydd roedden nhw'n gwybod beth oedd ar ddod. Fe aeth i bobman i geisio'r wybodaeth honno. Rwy'n cofio iddo ddweud wrthyf i ei fod wedi mynd i Lundain er mwyn mynd o amgylch yr holl lysgenadaethau a swyddfeydd yr is-genhadon i gael gwybod sut beth fyddai Ewrop y dyfodol. Rwy'n cofio iddo ddweud wrthyf hyd yn oed ei fod eisiau trefnu taith i Norwy gyda'i deulu gyda'r bwriad gwirioneddol o fynd at y ffin rhwng Sweden a Norwy i weld beth oedd yn digwydd ar y ffin honno. Er y byddwn ni'n gweld eisiau ei ddeallusrwydd a'i ffraethineb yma yn y Cynulliad hwn, nid yw hynny'n ddim o'i gymharu â cholled ei deulu yn ystod y cyfnod anodd hwn. Mae fy meddyliau a'm gweddïau gyda'i deulu nawr ac i'r dyfodol, ond un peth a wn yw y bydd ei fab yn tyfu i fyny i weld ei uchelgais yn cael ei gwireddu ryw bryd; rwy'n credu hynny. Efallai mai amser byr a gafodd Steffan, ond bydd ei etifeddiaeth yn parhau.
