"that voter turnout was unusually high, and queues were building up in some areas"
Not sure what the BBC meant when they said "voting is brisk" at various times yesterday.
My immediate thought was "they're seeing people go in, and come out, in a matter of minutes", ie as per previous election polls.
Someone mentioned on Twitter that the polling station was quite busy (as she was on her way into work at the BBC around lunchtime).
Of course, what one person 'broadcast' via Twitter does not guarantee to be mentioned (and as she was presumably in London) may not be matched elsewhere, so could easily be ignored.
I don't follow people on Twitter, but this was Martha Kearney's comments, with some later comments around 19:00 being reported on the Guardian's site, claiming she would be in trouble as her comments broke BBC policy on not 'broadcasting' comments (hers were from some political insiders with their views).
