00:04 - Some within the Labour Party are blaming public dissatisfaction with the Brexit process on their projected election defeat.
"It looks as if Brexit dominated. A lot of this was Brexit fatigue. People just wanted it over and done with," Labour finance spokesman John McDonnell told Sky News.

18:45 - Today's vote has been billed as the "Brexit election," with Boris Johnson seeking a majority that would get his withdrawal agreement across the line and allow Britain to leave the EU on January 31.

16:00 - It's arguably the most unpredictable election in years, with many voters prepared to abandon long-held party loyalties after three years of Brexit wrangling.
