The UK's Home Secretary, Theresa May MP, has said that the UK has no intention of granting an amnesty to illegal immigrants currently in the country. She says that this would 'send out the wrong message'.
A recent study by the London School of Economics suggested that there are about 1,000,000 people living illegally in the UK though, of course, no one is really sure. They are made up of those who entered the country illegally, often by boat or through the Channel Tunnel, and those who entered the country legally with a temporary visa but failed to leave when it expired.
