SIR - I refer to recent reports on membership of the BNP within the public sector, highlighted by the recent calls by leading union officials and heads of public services to ban any such employees from being members.

Whether you hate the BNP or not the fact is they now represent a not insignificant number of people in wards up and down the country and hold around 50 council seats, including some here in West Yorkshire.

The call to ban is an affront to democracy and instead of banning membership of a perfectly lawful political party shouldn't these leaders be addressing the very legitimate concerns of those increasing numbers of people who are voting for the BNP. Or is that too difficult?
