I am currently watching both BBC and ITV Yorkshire and Humberside live broadcasts.
I understand police have been called to polling stations in Leeds Southeast, Sheffield Attercliffe, and Castleford, after voters caused disturbances because of being locked out.
More coming in now ; Lock outs and voter protests in Hackney, Ealing North and Ilford in London, Birmingham Hodgehill, and Chester, where over 700 would-be voters have been threatened with arrest if they do not disperse.
It seems the problems have arisen through Returning Officers running out of voting slips, and also out of date electoral lists being used, so when the public turn up with their poll cards, their names do not appear on the registers.
There has been an evacuation from a vote count centre in Londonderry on a Security Alert. Apparently an old folks home nearby was also evacuated.
