Polling data is readily available on how members of the Labour across Britain voted in the Brexit referendum: 65% for remain. However, this exit poll includes Labour voters across Great Britain*, and particularly the relatively large, and heavily pro-remain constituency of Labour voters in Scotland. (It also includes Labour voters in Wales, but there is less evidence that Welsh voters would be overly distinct from English ones) Given that Scotland's politics of Brexit are distinct from that of other parts of the UK, is there any polling data on how Labour voters in England specifically voted in the 2016 referendum?
*The Labour party does not contest elections in Northern Ireland, and I am guessing, perhaps incorrectly that YouGov did not survey the extremely small semi-official grouping of Labour members residing in NI
