There will be calls for a specific criminal offence when the inquiry report is published but little or nothing will happen, maybe a watered down general “duty” introduced.
I've heard reports - from the judge who headed the contaminated blood inquiry - that he will be recommending a statutory "duty of candour" on public officials.
A legal duty to tell the truth.
Taken to its logical conclusion, like the shock headlines of risking jail for leaving your bins out - the offence actually being "not complying with the terms of the asbo" - it's not the initial crime that gets you jailed, but the lying afterwards.
