Operation Stack has existed for decades.
And what is the reason for the implementation of Operation Brock right now?
Inland border facility is in Ashford further up the m20. So it's not that. There is one planned for Dover, but that's not even been built yet.
I watched a news report today live on BBC News with the journalist talking about delays, whist standing in front of the entrance to the port of Dover. Only 4 of the 12 booths open, and not a queue in sight.
I was there (Folkestone) on Saturday night/Sunday morning. The two motorway junctions next the to Eurotunnel were closed and everyone was being diverted onto the local roads. It was specifically attributed to Operation Brock.
