Cameron says of his time in government: ‘We proved in an increasingly polarised age that politics wasn’t either/or – you could be pro-defence and pro-aid; pro-family and pro-equality; pro-public services and pro-fiscal prudence too. We demonstrated that you could take the difficult decisions and win elections – and that a government could achieve a lot in just six years.’ So why on earth did he turn British politics into just another either/or question?

When​ the Australian cricketers Steve Smith, David Warner and Cameron Bancroft were exposed tampering with the ball during last year’s test series in South Africa there was, along with all the faux outrage, some genuine incredulity.
