A senior Welsh Conservative source has told BBC Wales the party fears at least three losses - Gower, Vale of Clwyd and Cardiff North.

The source said two other seats - Aberconwy and Vale of Glamorgan were looking tight.

Asked if he thought the party was making any gains in Wales tonight, the source said: "No."

Labour sources are telling BBC Wales political editor Nick Servini there could possibly be a recount in Aberconwy.

Wales Office Minister Guto Bebb has been Aberconwy's MP since the seat was created in 2010.

Labour's Aberavon incumbent MP, Stephen Kinnock, criticises Theresa May's Conservative campaign while praising what "looks like" a positive result" for his party.

"They fought the worst Conservative campaign in living memory - inept, dismal," he said.

"The story of tonight is that Theresa May has with great hubris and arrogance, called a general election and it's backfired on her in a big way."

Labour incumbent Ian Lucas retains his seat in Wrexham.

Labour's Nia Griffith has held Llanelli. Ms Griffith is the Shadow Defence Secretary.

Labour candidate for Gower Tonia Antoniazzi says she's been encouraged by the increased turnout in the constituency.

The turnout is 73.4% up from 69.2% in 2015.

But she says "I'm not taking anything for granted. It's been a tough battle and we've been short of funds".

There have been whispers that the Conservatives could lose Gower, which they won last time by just 27 votes.

Pippa Bartolotti, Newport West Green Party candidate says the results so far suggest parties must now "talk to each other properly - like other European countries do".

We've heard a lot about Gower, but Labour is also confident of taking Aberconwy according to BBC Political Editor Laura Kuenssberg

UKIP are a little downbeat in Merthyr Tydfil.

The party secured its third largest share of the vote across Wales in the constituency at the last general election in 2015.

But what does tonight have in store for the party?

Counting is in full swing in Caerphilly where Plaid Cymru sources say they believe they may be relegated to third behind the Conservatives in second, with Labour's Wayne David likely to retain his seat.

More turnouts are coming in for Welsh constituencies, and so far all but one seat has seen an increase compared to the last general election.

• Swansea East - 60.17% up from 58% in 2015
• Swansea West - 65.7% up from 59.7% in 2015
• Delyn - 73% up from 69.9% in 2015
• Rhondda - 65.3% up from 60.9% in 2015

The exception to the rule so far is Cardiff North where turnout was 68.2%, down from 76.1% in 2015

Shadow Wales Office Minister Gerald Jones has said the jump in turnout could be down to young voters.

David Jones, Conservative Brexit minister and the incumbent for Clwyd West, says the exit poll "could clearly be better" but he said results coming in since the prediction that the Conservatives could fail to win an overall majority, suggest the forecast could be wrong.

He said more results were needed before a clear picture could be formed.

Blaenau Gwent's Labour AM, Welsh Government minister Alun Davies says if the exit poll forecast is correct and the Tories fail to win an overall majority, it would mean "Theresa May has no mandate" and that she "would have to resign in the morning".

Turnouts for some seats in Wales are up compared to 2015.

• In Vale of Glamorgan, the turnout was 72.2% - up from 71% in 2015

• Ogmore turnout 65.26%, up from 64%
• Merthyr Tydfil and Rhymney 61%, a big jump from 2015 when it was 53%
• Vale of Clwyd 68% up from the last general election when it was 63%
