Boiling A Frog by Christopher Brookmyre (Abacus 2000)

Given her pedigree, she was also a Tory target for accusations of selling out in endorsing Tony Blair's reforms. She had become yet another New Labour robot, they said, and had betrayed everything her father stood for simply to further her own career. Yeah, sure, and the band played "Believe it if You Like'. Labour politicians had always been accused of abandoning their principles in pursuit of power, since long before Tony Blair appeared on the scene. It was part of the Tories' time served pincer-movement strategy: if you took a hard line you were a dangerous lefty out to wreck the economy; if you softened your position, you were an unprincipled chancer who'd do anything for a sniff of power. The Tories knew they'd never face the same charge because they didn't have any principles in the first place. How do you ideologically compromise a stance built on greed, materialism and xenophobia?

Consequently, she didn't mourn Clause Four's passing. Holding on to it was a futile gesture of stubborn and misguided faith, like wearing the medal of some mediaeval saint whose canonisation had been rescinded. It was an anachronism and an impossible dream, but far more damaging, it was also a stick with which their enemies had too often beaten them.

Compromise was always depicted as a political sin by those in the grandstand. Those in the game knew that politics is compromise. If you want a party that believes in all the things you do, and with which you disagree on nothing, you'll have to start it yourself, and the membership is extremely unlikely ever to exceed single figures. In binary.
