Theresa May has set a trap for Labour – but she could fall into it herself

By backing Brexit – even a soft Brexit like Common Market 2.0 – we would see our voter base fragment to the SNP, Greens, Lib Dems and newly formed, explicitly anti-Brexit Change UK. Labour supporters would see a May/Corbyn deal as a betrayal, leading to a Lib Dem-style vote collapse. Labour would not pick up Leave voters to compensate. Just as Tory voters stuck with real austerity in 2015, not the ‘austerity-lite’ of Ed Miliband, so Leave voters would stick with the Tories, and would not be swayed by the halfway house of a customs union or single market membership.
