Leave are ahead in Wales after 19 European Union (EU) referendum results came in early Friday and with only four to go, BBC reported.
So far 689,603 (54.4%) have voted for 'Leave', compared to 578,917 (45.6%) for 'Remain'.
Several opposition Labour Party areas have backed Brexit, including Merthyr Tydfil, Newport, Caerphilly, Blaenau Gwent and Swansea.
Welsh Labour In campaign manager Lord Hain said the Tories invited a kicking in the poll "and are being given it".
Only three areas - Ceredigion, the Vale of Glamorgan and Monmouthshire - have voted for 'Remain'.
Turnout has been high at 71.7% for Wales.
Results in Wales will be announced on a council-by-council basis, before an overall result is announced in Connah's Quay, Flintshire.
