In the House of Commons in 1983 a black man is shown, seemingly an MP; there were no black MPs until 1987.
Despite being set in the 1980s and early 1990s, no attempt has been made to disguise the scenes shot in Central London, so modern cars and buses (as of 2003) are regularly seen behind the characters.
On the night of the 1992 election Brown speaks to Blair on his phone from his own constituency in Scotland. He tells him Peter (Mandelson) is with him. This is impossible as Mandelson will have been in Hartlepool (200 miles away) for his own election to parliament.
