Sir Emyr Jones Parry will chair the last final public debate
A last public question time session on more possible powers for the Welsh assembly will be held later at the National Eisteddfod in Bala, Gwynedd.
The meeting will be the final public event held by the All Wales Convention to gauge views on whether there is an appetite for more powers.
The session follows 23 events across Wales attended by almost 2,000 people since they began a year ago.
A report on the consultation process will be presented to ministers.
The event will be chaired by Sir Emyr Jones Parry, and he will be joined by two other members of the convention.
"We are now approaching the end of the road for the public consultation element of our work, but as a convention we have a long way to go yet," said Sir Emyr.
Over the past year the controversy over MPs' expenses has affected the debate, he said, with a general loss of faith in politicians.
The first meeting was held at the Pierhead in Cardiff
"We have held city centre roadshows, question time-style events and family days in community centres, discussing the issues with people who had seldom engaged in political debate," said Sir Emyr.
The convention's final report is due to go to the assembly government before the end of the year so a decision can be taken on whether to hold a referendum on more law-making powers.
The event will be held on the Welsh Assembly Government stand between 1400 - 1500 BST.
Public comments can still be made via the All Wales Convention website until Friday, 21 August.
