Despite the Tunisian government's efforts to root out corruption in the country, many activists believe that graft still plagues the North African country, as Adnen Chaouachi reports.

In November 2011, the Tunisian National Anti-Corruption Agency was founded by the first post-revolution authorities. This week, the agency signed a pact with 29 associations and non-governmental organizations to combat all forms of corruption in Tunisia.

"The instance needs the support of the civil society, the fourth estate, the judiciary system and parliament. We must work together for an efficient anti-corruption strategy. We're all concerned," said the agency's president Chawki Tabib.

Rafik Halouani, general coordinator of civil society network Mourakiboun, urged the government and legislators to protect whistleblowers who reveal illegal activities and expose corruption in different sectors. 

"In February 2017, a law was adopted by MPs. It criminalizes any retribution against whistleblowers. Yet, some citizens hesitate to denounce corruption. We must guarantee their anonymity and safety," he said.

Apart from Mourakiboun, IWatch is another anti-corruption Tunisian civil society organization founded in 2011 by young volunteers. Now they are launching an anti-corruption campaign.

Activists warn against the spread of corruption which could hamper economic growth and cause instability in Tunisia.

"Fighting corruption is our top priority. It delays local and foreign investments. Corruption in politics and the media threatens the democratic transition in Tunisia," said Iwatch activist Youssef Belgacem.

The spread of corruption sparked the Tunisian revolution in 2011. Six years on, fighting the scourge is still a challenge for both the authorities and civil society.
