Sunny weather and calm seas have meant the number of migrants attempting the dangerous crossing from northern France to the UK in small boats has risen sharply in the last week. In April this year, the UK agreed to provide 767 million euros to France over the next three years to reinforce policing along the coastline. But migrants, when they arrive in northern France, have often already crossed several different borders and they are determined to make the crossing to what they believe will be a better life in the UK. Our reporters met with migrants on the beach in Gravelines near Calais.
