Powell had also expressed his opposition to the Race Relations legislation being put into place by the Labour Prime Minister Harold Wilson at the time. After the "Rivers of Blood" speech, Powell was transformed into a national public figure and won huge support across the UK. Three days after the speech, on 23 April, as the Race Relations Bill was being debated in the House of Commons, 1,000 dockers marched on Westminster protesting against the "victimisation" of Powell, with slogans such as "we want Enoch Powell!" and "Enoch here, Enoch there, we want Enoch everywhere". The next day, 400 meat porters from Smithfield market handed in a 92-page petition in support of Powell, amidst other mass demonstrations of working-class support, much of it from trade unionists, in London and Wolverhampton. Conservative politician Michael Heseltine stated that in the aftermath of the "Rivers of blood" speech, if Enoch Powell had stood for leadership of the Conservative party he would have won "by a landslide" and if he had stood to be Prime Minister he would have won by a "national landslide". Powell made a speech in Morecambe on 11 October 1968 on the economy, setting out alternative, radical free-market policies that would later be called the 'Morecambe Budget'. Powell used the financial year of 1968–69 to show how income tax could be halved from 8s 3d to 4s 3d in the pound (basic rate cut from 41 to 21 per cent) and how capital gains tax and Selective Employment Tax could be abolished without reducing expenditure on defence or the social services. These tax reductions required a saving of £2,855,000,000 and this would be funded by eradicating losses in the nationalised industries and privatising the profit-making state concerns; ending all housing subsidies except for those who could not afford their own housing; ending all foreign aid; ending all grants and subsidies in agriculture; ending all assistance to development areas; ending all investment grants; and abolishing the National Economic Development Council and the Prices and Incomes Board. The cuts in taxation would also allow the state to borrow from the public to spend on capital projects such as hospitals and roads and spend on "the firm and humane treatment of criminals". In mid-1968, Powell's book "The House of Lords in the Middle Ages" was published after twenty years' work. At the press conference for its publication, Powell said if the government introduced a Bill to reform the Lords he would be its "resolute enemy".
