Watch: BBC crew captures moment migrants board small crowded boat to UK from France
The BBC's Home Affairs correspondent, Tom Symonds, was reporting live as a crowded migrant boat set sail for the UK from Calais in France.
He said French police made no attempt to stop the boat from leaving, but did stop another group of migrants from trying to get onto the water.
He also explained that it was unlikely that the boat would make it across the Channel, as a large French military or coastguard vessel was blocking the way.
