Row over Sangatte Refugee Camp in Calais

The refugee center issue between France and Britain has been ongoing for months, with overcrowding and illegal entry attempts into the UK being major concerns. The UN, led by High Commissioner Ruud Lubbers, has offered to screen the residents to distinguish genuine refugees from economic migrants. The center's proximity to the Channel Tunnel has led to increased illegal entry attempts, prompting discussions on its closure. French and British governments are in talks, with conditions for closure including tougher UK immigration policies. The fate of the current residents, mainly Afghans and Kurds, remains a pressing issue.
