This is the moment friends on a lads trip to France opened the back of their van to find two grinning migrants hiding inside -- asking "in England?"

Charlie Cox, 23, and five pals were parked up in a supermarket near Dunkirk when the father and son from Afghanistan sneaked into the back of their van.

They didn't notice until they'd driven 20 minutes to a nearby motocross track - still in France - for a day of racing bikes.

When they opened the back door of the van they found the pair tucked between their kit -- and filmed as the father appeared to ask "where about [in] England?"

The stowaways didn't realise they hadn't crossed into England since he'd jumped into the van - and was gutted and confused to discover he was still in France.

Charlie, an engineer from Stroud, said: "We'd just gone to grab a coffee and were in for about half an hour.

"We've come out, got back in the van, and driven about 20 minutes to the track.

"I've gone to get my bike out and opened the side door, and there are two immigrants in there.

"They had done something to the rear lock on the door and got in that way.

"They thought they were in England.

"I think they saw the GB on the car at the supermarket and thought that they would take their chances on it going to England.

"They were in there with us for about 20 minutes and didn't hear them - we didn't at all.

"We heard a thud when we broke heavily but we thought it was the bike hitting the bulkhead.

"Their English was pretty terrible but he smiled at me and said 'in England?' It looked like a father and son.

"I asked him 'why did you want to come here?' and he said he had family here.

"They were quite well presented. Obviously they were staying somewhere with a roof over their heads."

They were discovered at the motocross track at Loon-Plage on Wednesday morning.

The friends had all been on a week-long biking holiday across Europe.

The video shows the grinning pair being discovered and Charlie and his pals shouting "come on" and "what are you doing?".

One added: "Nice try though."

Charlie said the pair hung around for five minutes before walking off.

"They looked pretty devastated," he said.

"They were now in the middle of nowhere."
