Polish migrants have been an asset to the UK. They've set up businesses and paid all their taxes to the UK.
Granted there was already a strong Polish community of those who'd remained after helping the UK and her allies to defeat Hitler and they were able to offer some advice and support to newcomers, but the younger group worked hard when they arrived here, often taking work for which they were overqualified rather than claiming benefits.
washing cars and big issue selling is hardly what we are crying out for in this country
they only do it to get benefits and housing on top of their wage
