Trust in politicians under cloud as anti-corruption body concerns grow. I speak with Griffith University professor AJ Brown

The anti-corruption body Transparency International will today update its wish-list for a national integrity body amid concerns that it won't be properly resourced to fight corruption. 

The coalition's proposal for a Commonwealth Integrity Commission is seen as weak given that it won't be permitted to hold public hearings, won't take tips from the public and will only investigate when the evidence meets a high threshold. 

Griffith University professor AJ Brown - who's also on the Transparency International board - speaks with ABC's Peter Ryan.
