"We have done well as a country out of those who have come to make their homes here".
However, even those tough proposals could not disguise the U-turn.
Patrick McLoughlin, the Conservative Party chairman, called it a "day of chaos", saying: "Jeremy Corbyn's day has gone from bad to worse - with his "relaunch" descending further into chaos". After pointing out how May failed in revealing the Brexit planning, he will mention that the labour will not give any free pass to the government in negotiations.
"He suggested a new 100 per cent tax rate, which he U-turned on within hours".
The proposals were included in a speech by the Labour leader, which was originally created to clarify the party's position on immigration but appeared to be overtaken by events.
His comments were immediately denounced by Danny Blanchflower, a former adviser to the Labour leader and ex-Bank of England monetary policy committee member, who said it was "totally unworkable".
The chief executive of key Government contractors Capita (£2.7m) and G4S (£2.5m), for example, earned many times that sum previous year.
Mr Corbyn will also criticise the British government for failing to have a Brexit strategy.
He told Labour activists in Peterborough: "This is not about limiting aspiration or penalising success, it's about recognising that success is a collective effort and rewards must be shared".
"We would say a company that wished to recruit had to advertise openly rather than just going to a place of low wages to bring people in".
Later, the spokesman said: "He mis-spoke in that interview".
"It's something we are looking at".
Jeremy Corbyn, leader of the Labour Party in the United Kingdom, is toying with the idea of maximum wage laws to be imposed on the country's highest earners, The Guardian has reported.
In his speech, which was billed as a mayor reboot of his leadership as a leftwing populist, Corbyn said the United Kingdom "cannot afford to lose full access to the European markets on which so many British businesses and jobs depend". While all European Union citizens now resident in the United Kingdom should be given the right to remain, the right to work would have to be "negotiated" while other measures would be needed to ensure that workers particularly from central Europe were not brought in to "undercut existing working arrangements" and face "grotesque levels of exploitation".
But he declined to say whether he backed specific proposals from senior Labour MPs for a requirement for migrants to find jobs before coming to the United Kingdom or a two-tier system giving easier access for those with in-demand skills.
Asked by journalists whether he actively wanted to reduce levels of immigration, Corbyn declined to say he wanted an absolute reduction in numbers, instead highlighting the benefits of immigration and pointing out that Britain's ageing population required a younger workforce.
