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.
