Is there any difference in meaning if 'in' is replaced with 'on' or 'at'?
Mr Cameron's arrival in Downing Street marks the end of 13 years of Labour rule. The Conservative leader, who is six months younger than Tony Blair was when he won power in 1997, is the youngest prime minister since 1812 and the first Old Etonian to hold the office since the early 1960s.
I believe in the US and some other countries they prefer 'on' instead of 'in' when it comes to street.
