The vote backed proposals in a report by a GPC reform group led by former BMA chairman Dr Hamish Meldrum.
GPs at the conference argued that health systems across the UK had diverged to such an extent that England needed its own GPC group.
One Scottish GP told the conference that the UK conference was so Anglo-centric that he felt like he was 'intruding on English GPs' private grief' by listening to debates about the GP Forward View and other England-specific issues.
Former Wales LMC chairman Dr David Bailey spoke in favour of the creation of an English GPC, as did Wiltshire LMC member Dr Helena McKeown.
Under changes also backed by LMC leaders, in future years the UK GPC conference will be cut to a single day, and a one-day England LMCs conference will take place. The move will take effect from 2018, with next year's two-day UK LMCs conference set to take place in Edinburgh.
In other changes backed by GP leaders, LMCs will now take greater control of the GP Defence Fund.
