Since then Vanuatuan politics have been unstable, seeing a series of fractious coalition governments and the use of no confidence votes resulting in frequent changes of prime ministers. However, the democratic system as a whole has been maintained and Vanuatu remains a peaceful and reasonably prosperous state. Throughout most of the 1990s the UMP were in power, the prime ministership switching between UMP rivals Korman and Serge Vohor, and the UMP instituting a more free market approach to the economy, cutting the public sector, improving opportunities for Francophone Ni-Vanuatu and renewing ties with France. The government struggled however with splits within their NUP coalition partner and a series of strikes within the Civil Service in 1993-4, the latter dealt with by a wave of firings. Financial scandals dogged both Korman and Vohor, with the latter implicated in a scheme to sell Vanuatuan passports to foreigners.
