Last week the former British prime minister David Cameron made a visit to Sydney to headline a climate conference for Liberals and Nationals organised by the Coalition for Conservation, an organisation dedicated to creating a national platform for the environment across the centre right. He came bearing some important lessons for Liberals if we are to avoid the fate of the Conservatives, who lost three elections before empowering Cameron to modernise his own party.
I have personally heard speeches from three former or future Conservative British prime ministers during my lifetime: Margaret Thatcher in 1993 in the House of Lords, Boris Johnson while foreign secretary, at the Lowy Institute in Sydney, and last week David Cameron.
