If you wanted Liberal Democrat or Labour candidates to stand down at the General Election, where should you do it?

First let’s get a few things out of the way. This post concerns only two parties – the Liberal Democrats and Labour – and in one part of the UK – England. It also will not get drawn on who is to blame as to why there has been no pact between these two parties until now. And it will also not try to answer if this is ethically a good thing to do or not – you make that call as a reader.

The blog post seeks to answer the question: if either the Liberal Democrats or Labour (or, ideally, both) were to choose to stand down General Election candidates, where would they best do this?

This post has been prompted by the decision of Lib Dem candidate in Canterbury Tim Walker to stand down in favour of the Labour candidate Rosie Duffield there, and the Lib Dems threatening to nominate someone else and subject Tim to disciplinary action (transparency note: I know Tim personally, but have had no contact with him about his decision). Guy Kiddey, the Liberal Democrat candidate in High Peak, is threatening to do likewise. The Lib Dem candidate for Uxbridge & South Ruislip has stood down for personal reasons. The Lib Dems seem likely to put forward someone else in Canterbury, and I presume in Uxbridge & South Ruislip too.

But what if the Lib Dems and Labour did what Walker suggests, and were ready to stand down for each other?

There are three sorts of constituencies where this would make sense: easy two way marginals, complicated three way marginals, and free hits.

Easy two-way marginals

I mean easy in that is simple to see who should stand down.

Take the list of the top Conservative target seats:

Take a list of the Top Conservative seats to defend:

The pattern in all of these in England? These are two-way marginals, with the third party miles back.

It makes electoral sense for the Lib Dems to stand down in: Dudley North, Newcastle-under-Lyme, Crewe and Nantwich, Canterbury, Barrow and Furness, Keighley, Stroud, Bishop Auckland, Southampton Itchen, Pudsey, Hastings and Rye, Chipping Barnet, Thurrock, Calder Valley, Norwich North, Stoke-on-Trent South, Telford, Bolton West

It makes electoral sense for Labour to stand down in: Oxford West and Abingdon, Westmorland and Lonsdale, Richmond Park, St Ives

Or – if that is too hard in that it looks unbalanced – let the Lib Dems stand aside in 4 (Dudley North, Newcastle-under-Lyme, Crewe and Nantwich, Canterbury) and Labour in 4 (Oxford West and Abingdon, Westmorland and Lonsdale, Richmond Park, St Ives)

Complicated three way marginals

These are the most frustrating ones, and are places I have struggled with in my tactical voting guide. It would make sense for either Liberal Democrats or Labour to stand down in places like Kensington, Wimbledon, Wantage, Chelmsford, Colchester, Truro & Falmouth (non-exhaustive list). The problem here though is that while this would make electoral sense, trying to broker which party would stand down would be one hell of a task. So these ones are, for organisational reasons, probably left well alone.

Free hits

Every election throws up some unexpected results, and with pollster confused now in 2019 this election could be the same. Hence how about some standing down to try to remove especially pernicious Conservative MPs? In Wokingham (John Redwood), Esher & Walton (Dominic Raab) and North East Somerset (Jacob Rees Mogg) the Liberal Democrats are best placed to win, although each constituency is a long-ish shot. In Uxbridge and South Ruislip (Boris Johnson) and Chingford and Woodford Green (Iain Duncan Smith – actually marginal-ish, 44th on the Tory defence list) Labour is best placed to unseat the Tory.

So there you go. Were there to be a pact to stand down candidates, or even were one party to do this unilaterally (following Tim Walker’s lead) this is how and where to do it.
