September 2022 United Kingdom mini-budget
On 23 September 2022, the Chancellor of the Exchequer, Kwasi Kwarteng, delivered a Ministerial Statement entitled "The Growth Plan" to the House of Commons. Widely referred to in the media as a mini-budget (it not being an official budget statement), it contained a set of economic policies and tax cuts such as bringing forward the planned 1% cut in the basic rate of income tax to 19%; abolishing the highest (45%) rate of income tax in England, Wales and Northern Ireland; reversing a plan announced in March 2021 to increase corporation tax from 19% to 25% from April 2023; reversing the April 2022 increase in National Insurance; and cancelling the proposed Health and Social Care Levy.
