M25 weekend closure: drivers told to stick to diversion to avoid London Ulez charges

Motorway will be shut both ways between junctions nine and 10 from 9pm on Friday until 6am on Monday

Drivers tempted to bypass the official diversion for this weekend's M25 motorway closure have been warned of potential ultra-low emission zone (Ulez) charges if they stray off course.

The London orbital motorway is having its second ever planned closure, with a busy stretch in the south-west closed in both directions for works, potentially bringing long delays and congestion for thousands of drivers.
