[4][5] He ran unsuccessfully for the Cardiff North constituency at both of these elections,[6][7] but reduced the Labour majority to 540 votes in 2003.

The Conservative Party has backed that sort of devolution, so to oppose it now would make it easier for Labour to accuse us of hypocrisy.

[26] In February 2001 he was criticised by members of the Welsh Government for going on a skiing holiday in Salt Lake City to celebrate his engagement one week prior to the Assembly's half term recess.

[27][28] Morgan once again contested both Cardiff North and the South Wales Central list in the 2003 Welsh Assembly election.

[52] In 2020, Morgan campaigned for selection as a Conservative candidate for the South Wales Central constituency in the 2021 Senedd Election, but was not shortlisted.

[53][54] This decision was controversial, with Conservative MS for the South Wales East constituency Laura Anne Jones saying she was 'shocked and sorry' he was not selected, and Monmouthshire councillor Richard John saying "Anyone without an agenda would agree he has earned a place on the ballot paper.

[58] He also Chaired the Audit and Risk Assurance Committee of the Public Services Ombudsman from 2016 to 2020, and sat on the Audit Risk and Assurance Committee for the first Future Generations Commissioner for Wales between 2017 and 2023[59] In April 2023 Jonathan Morgan was appointed as Chair of Cwm Taf Morgannwg University Health Board[60] for a period of 4 years.
