The motion gives MPs until January 31, 2022 to provide proof they are double vaccinated or have a valid medical exemption. Those failing to comply will be suspended from attending parliament during a lockdown or similar restrictions.

On Tuesday, Moermond tabled a petition in parliament with 3,483 signatories claiming the Covid-19 vaccine “does not work and is a serious threat to health”. She has so far refused to disclose whether she is vaccinated.
