The government has been accused of taking a "wrecking ball" to the country by its cuts in public spending.
Len McCluskey, newly elected leader of the Unite union accused the government of going "far beyond" what was needed to rebalance the economy.
He told a conference in London organised by the Coalition of Resistance: "The anger that is unfurling across our country is not mindless.
"It is the legitimate expression of a people who feel that this government is taking a wrecking ball to our nation, going far beyond what is needed rebalance our books.
"They are using a global financial crisis to terrify the citizens of this country into meek acceptance of a raid on our schools, hospitals, services, jobs - the very fundamentals of our communities built up over 60 years of our tax and toil."
The Coalition of Resistance conference today was amazing. 1,300 delegates paid their £5. The British left set aside their usual bickering and agreed to launch a campaign of direct action to challenge the massive cuts coming from the Con-Dem neo-liberal regime.
From the SWP to the Climate Camp, groups sceptical of the Coalition have come on board.
There were some excellent speechs from the likes of Jeremy Corbyn, John McDonnell, Tony Benn and many others.
Many people worked hard to get the event off the ground, I am increasingly impressed by Green Party campaigns co-ordinator Romayne Phoenix, but hey I should mention another couple of hundred.
Good to see newly elected Unite General Secretary Len McCluskey quoting Engels and insisting that Britain's largest trade union is going to get stuck in. I am a Jerry Hicks loyalist to my marrow but Len did good.
I would urge everyone to get involved in the Coalition of Resistance and I will post videos as soon as I get them.
120 national committee were elected to take forward the resistance and the school students who took to the streets were loudly cheered on many occassions.
