France's interior minister says British police should be sent to Calais to help dissuade would-be illegal immigrants from trying to cross the channel.
There are around 2,500 migrants in Calais and the town's mayor has previously told MPs many are "prepared to die to come to England".
The situation in Calais is "completely untenable", David Hanson, Labour's shadow immigration minister has said.
Responding to the Mayor of Calais's appearance before the Home Affairs Select Committee, the MP said the Government should be doing more to tackle the "illegal route" into the UK.
But he said Natacha Bouchart needed to "acknowledge the role the French authorities should be playing to solve this problem".
He said: "If, as she claims, the people camped in Calais are not asylum seekers, why is the French Government not seeking to deport them?
“Of course we should be aiming for a European-wide approach to remove the migrant camp at Calais – there are serious questions about how people are able to cross Europe without being apprehended and end up at the border in the first place?
"But it is not good enough for the Mayor of Calais to seek to wash her hands of this problem and seek to simply move the border to Dover.”
