Sarah Dunant relives a road trip she took 50 years ago, travelling across the USA at a time when Roe v Wade was the talk of America, and revolution was in the air.

'I can only imagine what it must be like to be a woman living in America this week, she writes in the aftermath of the decision by the US Supreme Court - a decision which almost instantly makes abortion illegal in more than 20 US states.

She takes us back to 1972 and her travels across America in a beat-up car, when radical lawyers were honing their arguments to first present the case to the country's highest court.

'America's post-war abundance and energy, its style, its movies and its music saturated our youth', she says. 'We had the time of our lives - even the bad bits were good, we were living the dream'.

And, fifty years on, she reflects on what has happened to 'the fabric of this extraordinary country'.
