Anna Soubry, Heidi Allen and Sarah Wollaston all voted to hold the Referendum, to trigger Article 50 and to support the EU Withdrawal Bill. They have since been campaigning strenuously to overturn the result of the Referendum.
The ERG is defending the Referendum result and the 2017 manifesto, on which all three campaigned.
Parliament contracted out its sovereignty to the electorate, via the Referendum, on whether or not to leave the EU, therefore MPs have a duty to honour that result.
These three should resign their seats and stand for re-election as Independents.
The Labour MPs have apparently resigned for different reasons, and in a rather more dignified manner, but perhaps they should also stand as Independents.
From a purely personal view, the thought of local elections, yet alone a General Election, fills me with dread.
Two political parties, with two weak leaders, neither of whom will go, and a bunch of dissidents without a common aim.
