A catastrophic election defeat could lead to the parliamentary Conservative party tilting towards the populist right, Guardian analysis has indicated.
A projection of the seats the Conservatives would retain if there was a further two percentage point swing to Labour before election day, using data from Electoral Calculus, shows that about 40% of the remaining MPs would come from this wing of the party.
In less calamitous defeats – scenarios based on current polling levels, and on a situation where there is a two percentage point swing in favour of the Tories – the proportion would be nearer to 30%, roughly where it is now.
All of our current UK political parties are covering a wide enough range amongst their membership that they can form an opposition with themselves, never mind with a separate party :)
Your personal calibration may differ, but I’d say Labour cover between Left and Centre-Right, Lib-Dems between Centre-Left and Centre-Right, and Tories between Centre-Right and Far Right.
