Widespread disruption expected as fuel protestors target M4 Prince of Wales bridge
The demo will likely cause problems for those travelling between Wales and England on Monday
Drivers trying to cross between Wales and England could face widespread disruption.
Protesters are expected to block the M4 Prince of Wales bridge to demonstrate against rising petrol and diesel costs.
It's thought they plan to deliberately drive slowly in two lanes on motorways, leaving just one free.
Gwent Police say the protest is expected to last from 7am on Monday until 7pm.
Last week, the average cost of petrol rose to more than one-pound-91.
The RAC and the AA recently accused some retailers of not passing on a drop in the price of wholesale oil to drivers.
