Jackie Baillie says "you can expect an announcement relatively soon" as Lib Dem Shirley Williams brands the policy "a big mistake".
Rather than re-running the arguments of 2010, the party must start and sustain a debate about what a good, healthy economy looks like.
While Tim Farron heaped praise on Ed Miliband, Browne says that Labour is "intellectually lazy" and suffering from a "leadership void".
The shadow defence secretary is not impressed by the Lib Dem president's paean of praise to Ed Miliband in the New Statesman.
Ed Miliband has now sacrificed millions in donations, as well as one of his party’s main bargaining chips, without securing any concessions in return.
The Liberal Democrat president lavishes praise on the Labour leader and says "I don’t want join in with the Tories who compare him to Kinnock."
The emphasis that Miliband put on building more houses in his TUC speech suggests that a big announcement could soon follow.
The Labour leader says his trade union reforms mean Labour could become a party "not of 200,000 people, but 500,000 or many more."
If Labour is forced to compete with other progressive parties for millions in union funding, it is more likely to listen to what workers want.
Labour leader will say in his TUC speech that Cameron's declaration that trade unions are a "threat to our economy" was reminiscent of Thatcher's "the enemy within" and Romney's "47%".
