I've had a look at Leeds and get these results:
In 12 seats the BNP vote is static, hardly any change in the vote for the BNP.
In 10 seats their vote fell, most by 2/3 percent, one by 7 percent.
In 11 seats their vote increased marginally - 1/2 percent, the largest by 5.5 percent.
In 10 seats their overall vote is less than 5 percent.
In 6 seats between 5 and 10 percent'.
In 10 seats between 10 and 15 percent.
In 4 seats between 15 and 20 percent.
In two seats between 20 and 30 percent.
In one seat they got 37.5 percent of the vote.
The latter is almost exclusively white, as are the two others with 20 to 30 percent of the vote. These are areas on the outskirts of of the city.
