#GE1923 & #GE1929 both resulted in #LibLabPact, #GE2010 by #ConDemCoalition #GE2017 followed by #ConsParty pact with #DUP.

Informal coalition of #Liberals, #LabourParty & #IrishNationalists emerged in 1911, #ConsParty entered gov in 1914, in 1915 #HerbertAsquith was replaced by #DavidLloydGeorge.

Unlikely that #GPEW will end up in govt, if #LabourParty lose 100 seats, they'd be not far short of a majority, they'd likely have support of #SDLP, likely option of #LibLabPact or #LibLabCoalition, likely that would be a comfortable majority, #PlaidCymru & #APNI likely favourable.
