An anti-wind farm candidate has withdrawn from the Corby by-election campaign claiming he has achieved all his aims.
Journalist James Delingpole said he had run the "shortest and most successful election campaign of all time".
Green MP Caroline Lucas accused him of putting out "unscientific statements" as they debated green policies and renewable energy sources.
