I am not claiming to be blameless in what happened, but fundamentally I was not given a realistic chance to enact my policies by a very powerful economic establishment, coupled with a lack of political support.

Extracts from a 4,000-word essay. The claim "I was brought down by the left-wing economic establishment" is from the headline for a Telegraph covering article and is not directly used by Truss in her article. The nearest being her claim that "[l]arge parts of the media and the wider public sphere had become unfamiliar with key arguments about tax and economic policy and over time sentiment had shifted Left-wards".
