It's February 2013 and the ABC's Four Corners is back on air with a story that veritably screeches "gold Walkley". A prominent federal frontbencher, the program alleges, accepted secret payments from a company competing for a big government contract. The only problem, it turns out, is that the story was based on fraudulent documents concocted by a politically-motivated source.

Should Mark Scott, the ABC's managing director, resign?
