Magistrates who disagree with the 20mph speed limit imposed in Wales should quit, a court industry body has said.

The advice comes after a magistrate resigned because he refused to fine speeding motorists breaking the limit, which was introduced in March.

The new default national speed ban was introduced across Wales, with a 20mph limit for all roads in residential or built-up areas.

Drivers who are pulled over could be fined a minimum of £100, as well as receiving three penalty points on their licence.

Nicholas Colbourne, 66, from Wrexham, said the blanket imposition of the limit across all residential roads across Wales was “just farcical”.

An online petition against the scheme has amassed more than 460,000 signatures.
