I'll start a thread here. This article explains why I think it'll be close tonight in the Brecon and Radnorshire by-election.

Polls close in Brecon & Radnorshire: will the chickens come home for PM Johnson?
While we wait for counting to begin, I'll share what people are telling me here at the count and via other means.
The Liberal Democrats are hopeful but don't believe they're in landslide territory. They report a sense that Boris Johnson taking over as Prime Minister has had an impact.
The Lib Dems say they've been getting a positive response from 'old supporters and new allies' but one Lib Dem tells me 'the percentages at the end of this could well resemble the referendum tally, hopefully in our favour.'
Labour sources are expecting a bad night. They may be happy if they hold onto their deposit. I understand that all the way through the campaign they've seen their vote 'draining away' to the Lib Dems.
Conservative after Conservative tell me it'll be close. Possibly even recount territory. 'Our vote is strong,' said one 'and going out to vote for Chris [Davies]'
There's a bit of annoyance at the party centrally. Some Conservatives were disappointed that Boris Johnson didn't make more of his campaign stop in Brecon on Tuesday. A lot of activists were ready and waiting for him but he didn't go walkabout.
Some have also reported similar annoyance that Alun Cairns didn't campaign more than a visit to the Royal Welsh show which one said is remarkable given that he's the Secretary of State.
One Conservative: 'the whole thing will depend on Labour switchers. If the Brexit party take them we're in with a shout. If Libs have them then they've won by a mile.'
A prediction from a Labour source: Lib Dems win, Cons 2nd, Brexit 3rd, Labour 4th. But keeping their deposit.
Labour did not stand aside in the 'Remain alliance' but unofficially hope it succeeded. 'We want Boris to be defeated,' one source says.
Sources in parliament have heard there could be up to five Tory MPs ready to defect if the Lib Dems win tonight.
Another Conservative who's been phone canvassing feels the vote for Chris Davies is holding up. They think they may have picked up a few new voters who like Boris Johnson. But still think Lib Dems will narrowly win.
A Lib Dem victory by 2,500 votes they reckon.
Some hints the turnout could be 40-50%
Re: criticism of Alun Cairns: I'm told that he went campaigning at least twice as well as the Royal Welsh Show.
Powys council tell me turnout is expected to be announced between 0100 - 0130
The Brexit party believe they've done enough to lure Labour leave voters to vote for them.
Conservatives seem to be doing well in the smaller towns of Brecon and Radnorshire.
Conservatives are cheered after seeing another batch of boxes which look good for them. They still think it's going to be tight though.
Several Conservatives have now told me this has been a nasty campaign. 'The dirtiest campaign I've ever known,' said one. Including personal abuse.

Another Conservative: the boxes are looking better than we thought.
Labour source says early boxes are looking better for Conservatives than expected and worse for Brexit party than expected.
That seems to back up theory tactical voting has happened: Brexit party supporters going to Conservative, Labour to Lib Dems.
I should point out that's not what the Brexit party think has happened.
Conservatives feel they’ve won in Hay and Rhayader. Some think it’s ‘tight but ok... the towns will be the decider’
The acting returning office confirms that the final ballot box from the 93rd polling station in Brecon and Radnorshire has now arrived at the count.
Reports keep coming back that for every box that the Conservatives win there's another that the Lib Dems win. Neck and neck.
Brexit party sources acknowledge they’re likely to come third. Have supporters drifted back to the Tories? ‘We’re only three months old. These parties have big campaign machines.’
Post-watershed language: Lib Dems say Conservative claim they've won Hay is 'bollocks...they definitely haven't won Hay.'
Lib Dems say all sorts of boxes are showing big swings compared to their 2017 results. 'All the signs are pointing to a close result.'
Brexit party sources who've surveyed ballot boxes being verified think Lib Dems have won the by-election with half of the vote. Conservatives with a third. Brexit party 1 in 10 and Labour below that.
Ok everyone. I think I'm about to report the turning point. Bear in mind counting hasn't even begun yet but based on what the parties are telling me after surveying the ballot papers as they've been verified....
The crucial town of Ystradgynlais seems to have gone to the Lib Dems. 'We've lost Ystradgynlais,' says one Tory. 'That's us done.'
They go on: 'the Labour vote seems to have collapsed and gone to the Lib Dems. What we didn't want.'
Verification complete. Counting about to begin.
Lib Dem: 'I'm much more cheerful now than earlier on.'
Turnout: 59.72%
Lib Dems say Labour votes going to them
Tories say the likely result in Ystradgynlais is a big blow.
Tories: still tight, doesn't mean it's lost yet. But they're much less optimistic now.
Labour reckons it was voters in the lower part of the Swansea Valley helping the Lib Dems. 'What swung it for the Lib Dems was Labour votes in Ystradgynlais and Ystalyfera
Total number of verified votes in Brecon and Radnorshire by-election: 31,887, a turnout of 59.72%
. @roger_scully tells me it's the highest turnout in a parliamentary by-election this parliament
Conservative: it's too tight to call.
I have no idea about betting so I pass this on unaltered and without any explanation: ‘massive move on betfair conservatives just back in from 17-1 to 8-1 proper money changing hands.’
Also passing on this unaltered: ‘just to give some context to the crucial areas; the region of Ystalyfera that is within B&R is composed of just two housing estates. slim margins indeed’
I’m told they’re ‘pure Labour strongholds’ so showing how Labour votes have gone to Lib Dems in this by-election
Brecon and Radnorshire state of play at 0050: Counting is underway. Too close to call between Lib Dems and Tories but the Lib Dems look they have momentum behind them. Brexit party 3rd. Labour hoping to keep deposit.
Brexit party are happy with their likely 3rd place and not worried about 'splitting Brexit vote' - their aim is to remind Tories they're there and willing to 'take them apart' if they don't deliver Brexit.
