The UK government has tightened rules to prevent refugees arriving on small boats from claiming citizenship, as it continues to crack down on immigration.

Under UK law, it is now an offence to enter the country without permission. This is despite the UK being signatory to international law treaties, such as the 1951 UN Refugee Convention, which state that asylum seekers and refugees should not be penalised for illegal entry.

Britain has toughened up its rules to make it near impossible for small boat refugees to become UK citizens - ever. Now, anyone who arrives in the UK by making the perilous journey - via boat or hiding beneath vehicles on ferries - will normally not be allowed citizenship.
