The Budget Protest League was a British pressure group formed in June 1909 and led by Walter Long to oppose David Lloyd George's (nicknamed the 'Welsh Wizrd') "People's Budget" outside of Parliament.
The League attacked the Budget's Finance (1909-10) Act 1910 as Socialist because of its income tax rises, increased death duties, and a land value tax in order to redistribute this to old age pensions. It was not linked to tariff reform. It produced posters outlining its opposition to Lloyd George and the Budget.
In reaction to the formation of this League there was formed a Budget League—chaired by Winston Churchill—to promote the "People's Budget".
