'No immigration link' to UK unemployment © Reuters / Russell Cheyne Immigration has little or no impact on the number of people unemployed in the UK, according to a report. A study by the National Institute of Economic and Social Research (Niesr) showed that number of immigrants coming to the UK is not linked with the number of people claiming jobless benefits. But the Niesr report did concede that it is still not known whether an increase in the number of migrants coming to the UK leads to a fall in the number of low-skilled jobs available to British workers. A separate report by the Government's Migration Advisory Committee (Mac) claimed there are 23 fewer jobs for British workers for every 100 migrants from outside the EU. The Mac report also added: "Migrants are found to increase wages at the top of the UK wage distribution and to lower wages at the bottom of the distribution."
