Billionaire cardboard king Richard Pratt faces jail over accusations he lied to a competition watchdog investigation into a price-fixing cartel. 

The Visy boss and Carlton Football Club president was charged on summons yesterday with giving false and misleading evidence to an Australian Competition and Consumer Commission (ACCC) hearing in 2005. 

In the summons lodged with the Federal Court, the ACCC charged Mr Pratt with breaching the Trade Practices Act by denying knowledge of a price-fixing deal with rival cardboard manufacturer Amcor.
