Thanks for joining us. We're wrapping up our live page now.

It's been a night of fast-moving developments across East and West Sussex.

The Conservatives have lost nine seats - five to the Lib Dems and four to Labour. The Green Party held on to their only seat in the patch, Brighton Pavilion.

You can keep up with the ongoing national election coverage here.

The Green Party has held onto Brighton Pavilion, following the departure of Caroline Lucas.

Sian Berry, former leader of the party, won with 28,809 votes (55%).

Her closest rival was Labour's Tom Gray, who took 14,519 votes (27.7%).

Ms Lucas, previously the only Green MP in the country, held the seat for 14 years before stepping down at this election.

The polls pointed to a pretty rough night for the Conservatives in the South East, but this morning they amount to a complete and utter redrawing of the electoral map.

There were always seats that were likely to change in Worthing, Hastings, Guildford, and East Thanet. That said, nearly all of the seats I had pinned as those that would be lost for the Conservatives on a bad night - think Chichester, Dorking and Horley, Surrey Heath, and Gravesham - have fallen as well.

The results are particularly rough in Kent, where I had seven "bad night seats", of which the Conservatives have so far lost six.

This also suggests something about how the Conservatives have lost this election - and we should be thinking of this as a Conservative loss as much as a Labour gain.

I calculated seats as either likely to change, or ones that might change with one simple question. Is there only one genuine challenger to the Conservatives?

Where there was one obvious place for the anti-Conservative vote to fall behind, the challenger has more often than not lost. This suggests a) an amount of tactical voting and b) an electorate more focused on kicking out the Conservatives, than backing Labour.

It's been a great night for Labour in Sussex, but an even better night for the Lib Dems.

The Lib Dems have gained five seats: Chichester, Eastbourne, Mid Sussex, Lewes and Horsham.

Labour has gained four: Crawley, Hastings & Rye, West Worthing, plus East Worthing & Shoreham.

They were all gained from the Conservatives.

Education Secretary Gillian Keegan lost her seat to the Lib Dems in Chichester, while the Green Party held onto Brighton Pavilion following the departure of Caroline Lucas.
