When the GMB asked for Progress to be outlawed, the response was
"We are a party that is reaching out to people, gaining new supporters and offering real change for the country in these tough times. The Labour Party is a broad church and we are not in the business of excluding people."
Labour leader Ed Miliband was also clearly in support, telling the Independent that “I believe in an open and inclusive party, reaching out to people, not for pushing people away. That certainly does not mean excluding or proscribing organisations like Progress which contribute to the debate."
In 2013, Len McCluskey, general secretary of Unite the Union, claimed Progress was manipulating the selection procedures for Labour parliamentary candidates to get its candidates selected. Progress responded: "Progress helps to train and mentor candidates going for selection, to whom we do not give money. The details are open, plainly explained on our website and approved by a strategy board elected by our members."
Strangely enough, it doesn't seem to apply to Momentum.
Progress was/is funded by Lord Sainsbury, who gave it £2 million out of its £3 million.
