BNP supporters have been told to breed more to increase the number of white people living in Britain.
After the party lost every seat it contested in the local elections, a post on the party's website suggests readers "engage in making babies."
The article, by Nothernscot, claims that 51% of America's population is "non-white", adding: "So we must look at ways of building up the white population in Britain."
The author suggests more immigration by white people, before adding: "The second way is more fun. I would suggest that BNP members and nationalists across the schools of nationalism engage in making babies.
"I know, by now you will be giggling over this suggestion. But think about it, nationalists need to buck the trend of 1.8 children per white household. We need to aim between 3 and 4 children each if not more.
"And the bonus is that making babies is fun.
"So fellow nationalists, less TV and more fun! Let’s do our bit for Britain and our race."
Nick Griffin's party is down to two councillors in the entire country after losing its final county council seat in Lancashire in Thursday's local elections.
Griffin was left complaining about electoral fraud after a defeat for his candidate in Cumbria.
The party still has two borough councillors in England, one each on Charnwood and Pendle councils.
