the end of the Six O'Clock News on the same day. For a while Sian Williams filled in as co-presenter, but on 3 December 2007 the programme went single-headed, with George Alagiah as main presenter, and Sian Williams as deputy presenter. A few months into the new arrangement Fiona Bruce took over from Sian as the main Friday presenter. On 28 January 2008, the programme moved studios, from N6 to TC7, as part of a restructuring across BBC News. On 21 April 2008 the programmes, along with the rest of BBC News, underwent a refresh, taking on new titles and a new set. On 17 March 2013, the BBC News at Six bulletin presented by Sophie Raworth was the final programme to be broadcast from TC7 in BBC Television Centre, after BBC Breakfast and Newsnight vacated the studio in 2012. The studio was demolished later in 2013 as part of the redevelopment of the site. On 18 March 2013, the programme moved to Broadcasting House, along with the BBC News channel and the other BBC One bulletins, and began broadcasting in high-definition. Alagiah was diagnosed with bowel cancer in 2014, and took leave from presenting duties. Raworth and Bruce were the main cover presenters during this time, which also saw regular appearances from Reeta Chakrabarti and Jane Hill. Alagiah returned in late 2015, but saw his cancer return in 2018, and once again took leave to undergo further treatment. Raworth once again covered Alagiah during his absence, with Bruce, Chakrabarti, Hill and Clive Myrie also regularly appearing on the programme. Alagiah returned to his presenting duties in January 2019. After eleven years in the role, in January 2019, Fiona Bruce stepped down as the programme's regular presenter on Fridays in order to replace David Dimbleby on Question Time. Sophie Raworth serves as the regular presenters on Fridays, with Bruce usually appearing on the programme on a Monday and as a backup relief presenter on Tuesdays and Wednesdays.
