If Labour is to have any chance of winning in 2020 then having a credible Leader and a sound, well thought through political strategy will be vitally important but some good old fashioned localised tactics are also essential. In 2010 and 2015 the Tories won a number of seats by applying some effective local tactics. To Labour needs to get back to being more tactically aware and astute.
In order to win or retain marginal seats in 2020:
CLPs must be allowed to select as early as possible to allow candidates to become active, develop local campaign issues, recruit new members and build a supporters' network
PPCs should adopt a policy of 'extreme 'localism' - does your hospital need to charge for parking? What is policing like in particular wards? Are there car parking issues on a particular street? They should be encouraged to focus a campaign on local community issues as much large macro issues.
Adopt a policy of positive campaigning - PPCs should resist the temptation to slag off their opponents and should focus on issues and not personalities
Hard working people like hard working candidates - PPCs should regularly provide local people with evidence of their endeavours and of the impact they have had and are having.
There must be no 'no-go' areas of the constituency in terms of canvassing and campaigning.
