The deputy contest as it stands would need to go no further as currently only Angela Rayner is on the ballot. She's likely to face at least a couple of challengers, but predicting the final ballot is tough. The hard left candidate here is much less popular than Long-Bailey, but one would expect Burgon to qualify. The race baiters will be keen on Dawn Butler progressing, otherwise they'll decry wacism.
To qualify candidates for both posts require either 33 nominations from Constituency Labour Parties (CLPs) or 3 nominations from Labour affiliate groups, two of which must be trade unions.
