Eurotunnel's truck shuttle service is subject to disruption again today following "an unplanned Tunnel inspection", the operator said without giving any further details.
It is not known whether the incident is related to the suspected presence of migrants in the Tunnel or concerns a technical issue.
French police last night had to deal with another mass intrusion attempt at the Channel Tunnel site at Coquelles involving around 500 migrants.
As Lloyd's Loading List.com was going to press, Eurotunnel warned its freight customers travelling from France that the journey from check-in to arrival in the UK will take approximately five hours.
For ex-UK traffic here is a waiting time of approximately 60 minutes before check-in and the journey from check-in to arrival in the France will take approximately three and a half hours.
But Kent Police have not had to re-activate Operation Stack on the M20 which was stood down last weekend.
In its latest tweet, P&O Ferries Freight said the company's Dover-Calais services are within 20 minutes of schedule.
As for the MyFerryLink dispute, attention turns to a meeting today of the Syndicat Maritime Nord seamen's union-led SCOP SeaFrance workers co-operative which was liquidated by a commercial court last Friday.
This triggered angry protests on Friday afternoon with the ring road leading to the Port of Calais blocked by burning tyres for a brief period while traffic was also brought to a near standstill on the nearby A16 motorway.
Today's meeting could lead to a fresh call to action but with ex-MyFerryLink workers without pay since 29 June and SCOP SeaFrance liquidated, there is perhaps now greater urgency for them to listen to DFDS' job offer to employ more than 200 staff, one observer said.
