2000s

The beginning of the new show. When Rose returns from her trips, a year had passed on Earth, so episodes taking place in 2006 were broadcast in 2005. By this time the general human population has evidence of the existence of aliens, though some see it as a hoax. Harriet Jones is the Prime Minister of the UK and Margaret Blaine is the Lord Mayor of Cardiff. The British government has a top-secret department, Torchwood, where they study alien technology.
