He's yesterday's man. I can't see the UK going for a bloke who looks like he's being parachuted in because there's no-one else to do the job. He's not got especially huge political gravitas. There's plenty of talent in the current PLP and if...big if (not going to happen)...Owen Smith wins then there would at least be a credible and competent opposition to bring the government to account.
Probably right and heard an interview with Owen Smith recently and he seemed to have some good ideas.
