Levelling-up policy of the Conservative government
"Levelling up" was a political policy first articulated in the 2019 Conservative Party manifesto that aimed to reduce the imbalances, primarily economic, between areas and social groups across the United Kingdom. It sought to do so without acting to the detriment of prosperous areas, such as much of South East England.
