Channel Migrants: New Update.

Now the boats on the French side have gone dark. 

You could excuse the UK boats, given the political sensitive nature of the migrant crossings. You might want to avoid the public knowing where the boats are landing, or how many times they stop in the channel, so you can't count the dinghies.

But what incentive is there on the French side to go dark? Unless the British side has put pressure on the French to make the crossings harder to track.

Why?
