The rival factions at war over Labour’s leadership contest

Which factions have the most influence in the Labour leadership and deputy leadership contest? The biggest split in the party is between the pressure group Progress and those with links to trade unions. Their respective outlooks are often perceived as being mutually exclusive, and the way the leadership contest is shaping up seems to suggest that this is true. Here is how the party breaks down between those two political poles, both in the 2010 contest and the one taking place currently. Around 80 of the 232 MPs in the Parliamentary Labour Party have taken part in Progress events over the last five years according to its website.
