The NMP is a marginal party and was only successful during the 1971 Dutch general election.
Several months after the elections one of its MPs, De Jong, came into conflict with the party's chair, Te Pas, because he was involved in lawsuits over corruption.
It is fiscally conservative and seeks to reduce bureaucracy and government debt.
Furthermore, it wants to end "car bullying", that is taxes on petrol, driven kilometers and car-purchases.
It advocates limited migration into the EU and cutting spending on development cooperation.
