I thought I just did.
Read it again :
We owe the Polish nation nothing.
And Poland owes us a debt of gratitude for declaring war on Germany as a direct result of Germany's attack on Poland.
We are however, indebted to the millions from the Commonwealth Countries who came to our aid. Including the largest volunteer army in history – the 2 million strong Indian army.
Shame that we appear to have forgotten their contributions, and yet we are so keen to welcome with open arms those to whom we owe nothing.
We owe the Poles no more, than what is owed to all those who fought for the allies in WW2. And if you want to talk numbers, then India contributed far more than Poland. So if you want to "allow economic migrants in to the country" on the basis of what their country did in WW2, then India should be well above Poland.
Unless of course, you are some sort of racist.
