Coalition party D66 has called for MPs who refuse to publish outside sources of income to be suspended until they comply with the rules.

D66 MP Joost Sneller said his colleagues should not be allowed to act with impunity by returning to parliament after a short suspension with no further sanction.

In October Forum voor Democatie (FVD) leader Thierry Baudet was barred from the chamber for seven days after MPs voted to censure him for not declaring his membership of the board of Amsterdam Media Group. The company’s subsidiaries include Baudet’s publisher, Amsterdam Books.

“At the moment an MP can go back to work without publishing his outside roles,” Sneller told RTL.

“That’s why I want offenders to be sanctioned, for example with a suspension that is only lifted once the MP complies with the rules or gives up their external role.”
