In 1997, the referendum on devolution scraped through on a minor majority – with the Welsh Conservatives campaigning for a 'no' vote.
Daniel Hewitt goes to the Senedd to speak to the party's leader Nick Bourne about why he and the Welsh Conservatives have had a change of heart this time round.
Hewitt also speaks to Cardiff Assembly Member Jonathan Morgan about how the 1997 vote affected his career and Richard Wyn Jones about what the Assembly referendum will mean for the Conservatives in Welsh politics.
Daniel Hewitt is one of our regular politics bloggers. He is a trainee broadcast journalist at Cardiff University and helps run the Politics Wales website here.
