Steffan Lewis, Plaid Cymru Assembly member for the South Wales East region, has died aged 34.
Lewis, one of the youngest ever members of the Welsh Assembly, was diagnosed with bowel cancer in late 2017. He is survived by his wife, Shona, and his son Celyn, who described him as “our rock, our anchor, and most certainly our hero”.
Politicians from across Welsh politics played tribute to Lewis, with Plaid Cymru’s leader Adam Price describing him as “our brightest star”.
As Lewis was elected via the additional member system, he will be automatically replaced by another member of Plaid Cymru in due course.
