The French authorities in Calais have defended their decision to prevent an aid convoy of about 200 vehicles leaving Dover on its way to enter France.
The Pas-de-Calais authorities said they had issued the ban for various reasons including the potential for the convoy to "generate violent episodes"; and a lack of available police officers because of the current European football championships.
They also said the numbers of vehicles involved could "facilitate the intrusion of migrants".
"In these circumstances, the Prefect of Pas-de-Calais considered only the prohibition of any event is likely to effectively prevent public disorders that may occur.
"Moreover, any convoy on roads and highways, from Great Britain to Calais to slow or block the flow and constituting a public event, is prohibited."
