RORO ships are used by British car manufacturers as they operate their factories on a just in time basis so that they don’t have a big holding of car parts as the majority of parts come into the UK through the docks in Southampton. The idea behind this is to keep costs down, but who knows what will happen once we leave the European Union at the end of January as they only can run the assembly lines for 4 hours and once they have run out of parts they will have to stop production of cars all factory staff will have to stop work, if there is a long delay in getting parts to the factories. Other manufacturers will also be affected but probably not as bad as car manufacturers. No doubt it will put up the price of a lot of things but it may cause a lot of industries to close.
Brexit was one of the dumbest things to happen in this country, there was no thought given to the fact that the British public would be stupid enough to vote to leave the European Union, the whole thing is a complete and utter Tory mess, unfortunately we have them in power for another 5 years. ☹️
