Well, Nigel, in each of the last four or five years, proven cases of electoral fraud have been in single figures every year (very checkable).

The very fact that you accept that there are proven cases is also acceptance that your earlier claim: there's no electoral fraud in this country was untrue. And according to you it was "very checkable". Obviously, as on previous occasions, you committed yourself to print without checking your facts in the belief that a strongly asserted statement would be accepted as 'fact'.
