Suella Braverman ‘s Home Office has called for Britain to toughen immigration rules to help cut record migration levels . Plans include charging migrant workers an annual £2,000 fee for using the NHS and increasing the amount they must earn to qualify for a visa. Yet Chancellor Jeremy Hunt is resistant to tightening the system in case it impacts his efforts to get the economy back on course. A source told Express.co.uk : ‘The points-based system is far too generous. Other countries think we are too generous. ‘We need to make changes to make it tougher, such as on the health surcharge and raising the salary threshold, but the Treasury is the block.’ POLL: Should migrant workers pay £2,000 for NHS treatment? (Image: Getty) The New Conservatives Group launched a report on Monday calling for Prime Minister Rishi Sunak to deliver the Party’s 2019 manifesto and cut net migration figures. Net migration figures have reached 606,000 which is more than six times the level the Conservatives promised. The report set out a 12-point plan which includes increasing the health surcharge, which currently is charged at £624 a year. A source told Express.co.uk that increasing this is £2,000 would be a ‘fairer’ reflection of the costs. They have also called for the salary threshold to be increased from £26,200 to £38,000 as ministers believe it is too low, meaning almost everyone qualifies. Ms Braverman was asked about raising the salary threshold in the House of Commons and admitted ‘net migration is too high’ and numbers need to be reduced. She added: ‘We expect net migration to return to sustainable levels over time and immigration policy is under constant review.’ So what do YOU think?
