The programme promises to combine serious coverage mixed with light relief until 6am.Sky News
Veteran news editor Adam Boulton partners with Sophy Ridge to lead the election charge on Sky News, beginning at 9pm. They will be supported by live coverage from 300 constituencies.
Sky’s results night will extend to Snapchat from 10pm with rolling coverage on the picture and video sharing platform.
First indication of results
The result of a joint BBC, ITV and Sky exit poll will be released at 10pm – as soon as polling stations close.
The survey will be taken from 144 polling stations across Britain, asking voters at these stations to mark a mock ballot paper to show how they have voted.
Similar exit polls have correctly predicted who would take the keys to Number 10 in the last five elections, and in 2005 and 2010 came extremely close to predicting the exact number of seats.
