Hundreds of roads and streets where a 20mph speed limit was introduced under a controversial law could be returned to 30mph, as the Labour-led government admitted mistakes had been made over the policy.

The Welsh government denied it had performed a U-turn and insisted the default 20mph for roads in built-up areas would remain to prevent deaths and save the NHS money.
