MOT on the rover p5b. No tax and no tax disc.

I took the rover for its MOT today and it passed with no advisories. Due to its status as a historic vehicle (a reminder of when this country had a thriving car manufacturing industry) it qualifies for free road tax. Its tax disc is marked as no payment made. The EU in another interference in English affairs are proposing to do away with tax discs,our weak government will go along with this as they allow the Germans and others to do more damage to this country in peacetime than they ever did in war.
How long before these parasites want old cars off the road ?
