The four Rs of a scandal: revelation, rage, responsibility and, finally, resignation. With a theatrical ritualism, in just 72 hours earlier this month, the high-flying careers of Les Hinton, Rebekah Brooks, Sir Paul Stephenson and John Yates tumbled from the branches of power. High-hanging fruit sent crashing to earth; venues as varied as Westminster corridors to stock market floors were spattered by the impact.
Were there a fifth R to this arc of opprobrium it would be this: rumour. Were they forced out? Were they victims? Before their sword-impaled bodies had even been dragged from the stage theories swirled. Resignation is, by nature, an act clouded in innuendo, encompassing at times contradictory motives: lofty moral stands and base calculation, self-sacrifice and self-preservation. Both maverick and martyr raise the same flag, while true motives and consequences often remain deeply private and unique.
If, as it is said, the art of a good resignation is timing, then it is fitting that this week a BBC documentary airs on the subject. My Resignation looks behind the headlines at some of the most famous acts of quitting in the past few decades: Home Secretary Jacqui Smith, toppled by the expenses scandal; Lord Luce, becoming a casualty of the Falklands invasion; Alastair Campbell, walking away from No 10; and the BBC's director general Greg Dyke, condemned by the Hutton inquiry.
Yet perhaps the most interesting aspect of resignation is not watching the powerful become suddenly powerless, but the inverse. The junior anaesthetist Dr Stephen Bolsin blew the whistle on infant death rates at Bristol Royal Infirmary in 1995, sparking a public inquiry and saving countless lives. While the civil servant Katharine Gun attempted to avert the Iraq war by leaking information about US diplomatic blackmail, provoking international outrage.
It is an illuminating aside that our social conventions dictate that those at the top of the ladder should take responsibility by committing career hara-kiri. Yet, for the toiling masses, being responsible is deemed to be about keeping your head down and avoiding taking stands.
Meanwhile, the nature of our existence demands that moral considerations compete with less celestial concerns. Greg Dyke said: "It was interesting that the only two people who left the BBC at that time were the only two who didn't have a mortgage." When I resigned as a reporter at the Daily Star over what I perceived to be deeply irresponsible journalism – a tale also featured in Wednesday's documentary – the question I was asked most often was: "Have you won the lottery?"
Hollywood has long recognised the romance of a principled resignation; we've all seen the steel-jawed cop slide his gun and badge across the desk before pacing into the night with just his fists and wits for protection. It's hard to explain to the uninitiated how deliciously subversive and self-affirming it feels to leap blindly from a cliff, just praying you hit water. And it's only when your feet hit the seabed that you recognise The End you feared so much was, in fact, the marker for a new beginning.
'My Resignation' is on BBC 4 on Wednesday, 9pm
