Put that case to the people of this country and win a general election to provide a decent, better society for all. Thank you very much.>>
The reason they don't see Corbyn as a credible leader. That's also Smith's main pitch to the Labor Party membership. His bid may have taken a knock with the CWU's declaration. Unions are seen as Corbyn's power base to lose, but to cause an upset in September's vote Smith must make some significant inroads.
