The furore over sexual harassment at Westminster, which this week led to the main party leaders agreeing to set up an independent grievance procedure, is not about sexual banter – the older guy who might touch your breast in a pub, or grab your knee, or make a lewd remark.

All women of my generation are familiar with this experience and know how to write it off, though it is a pity it’s still happening. Fundamentally, it is about sex and power, sometimes the power to make or break the career of a young woman – or man.
