Norfolk is not usually an exciting place to watch during election night but could this time there be change? The county is facing some pretty tight contests. Eight out of nine seats were Conservative last time, mainly with huge majorities. But the polls suggest that they could be slashed. Martha Kearney has gone on a road trip through some of those constituencies, starting in Waveney Valley, where there is attention on the co-leader of the Greens being one of the candidates. A full list of candidates in all the seats is on the BBC News website.
