of Canary Wharf", the Institute feels it must "learn by heart" a lesson about its own arrogance. It was later revealed that the London branch of Torchwood, called Torchwood One, lost 796 members of staff and was ultimately ordered to close by Queen Elizabeth II. The threat is ended when the Doctor and Rose Tyler use Torchwood One's equipment to banish the Daleks and Cybermen into the Void between worlds and end the invasion. In "The Runaway Bride", it is revealed that the London-based security firm "H. C. Clements" (which employed secretary Donna Noble (Catherine Tate), who inexplicably materialised in the TARDIS just as she was about to get married) was a front company for the Torchwood Institute. On a restricted basement level of the company situated beneath the Thames Barrier was a secret laboratory which the Institute used to recreate ancient "Huon particles". Over a period of months, H. C. Clements' Human Resources Manager, Lance Bennett (Don Gilet), had courted and poisoned Donna with Huon particles, intending to sacrifice her to the Empress of the Racnoss (Sarah Parish). It would appear that Lance was not acting on behalf of the institute, and the lab was in disuse since the Battle of Canary Wharf and the Queen's official closure of Torchwood One. In 2007, following Torchwood One's closure, Torchwood Three leader Captain Jack Harkness allows former Torchwood One researcher Ianto Jones (Gareth David-Lloyd) to join his team and is no longer working under the authority of the headquarters in London; he is the de facto leader of the entire organisation. This team worked together until later the same year, when the hiring of policewoman Gwen Cooper (Eve Myles) coincided with the suicide of second-in-command Suzie Costello. In "The Sound of Drums", Jack indicates to the Doctor that, with Torchwood One gone, fewer than ten staff remain (between Wales and Scotland). He mentions that he rebuilt the Institute "in the Doctor's honour", with a new regime and a less aggressive stance. Outside the institute's small workforce, journalists such as Vivien Rook (Nichola McAuliffe) of The Sunday Mirror investigate controversial figures such as Harold Saxon (John Simm) on behalf of the institute. Saxon sent Torchwood Three on a 'wild goose chase' to the Himalayas to prevent them from helping Jack or the Doctor. Torchwood Three later fought against the Daleks in their second invasion of Earth. Torchwood used the rift to make
