A PLANNED 'go-slow' by pro-Brexit lorry drivers failed to cause disruption on the M4 on Friday evening.

Around 100 protesters were planning to cause chaos on the motorway around the Prince of Wales Bridge over fears the UK's March 29 exit date from the European Union would be postponed or cancelled altogether.

They had planned to set off from Magor services at 6pm on Friday.

But the widespread disruption they had forecast failed to materialise.

The 'Great British road block south Wales' – directed largely through social media – was intended to create a rolling road block on a stretch of road which is routinely affected by congestion each morning and evening.

The M4 protest was part of a series of wider show of dissent by leave-voting HGV drivers across the UK.
