New AM for Alyn and Deeside Jack Sargeant made his maiden speech in the Senedd.
The 23 year old is the youngest assembly member in the Senedd and won the seat, previously held by his father Carl who was found dead in November.
It's thought he took his own life.
Jack Sargeant paid tribute to his father in his first speech in the Senedd.
In the speech he also said he would oversee inquiries into the handling of allegations of innapropriate conduct against the former Cabinet Member for Communities.
Carl Sargeant was sacked by the First Minister days before his death.
AMs in the chamber applauded Mr Sargeant at the beginning and gave him a standing ovation at the end of his speech.
