The 1997 General Election is called 

Here is 1 hour and 21 minutes of off-air BBC One from Monday 17 March 1997, running from 11:59 AM to 1:20 PM. After the end of 'Change That', there is a routine News bulletin. But with John Major having gone to Buckingham Palace, the BBC decide to replace 'The Alphabet Game' and 'Going for a Song' with a special edition of 'Westminster with Nick Ross' to cover the news.
John Major duly announces the election date. The BBC allow the five minute scheduled edition of 'The Weather Show' to go out, then the One'o'clock News covers the election including live interviews with Tony Blair and Paddy Ashdown.
