A surge in sign ups to the Enough is Enough campaign caused its website to crash briefly on Monday, organisers have said.
Enough is Enough, a new left-wing policy platform for the cost of living crisis, is backed by unions, politicians and commentators.
The five point manifesto calls for: A real pay rise, energy bills to be cut, food poverty to be ended, ‘decent’ homes for all, and higher tax for the wealthy.
Eddie Dempsey, RMT union deputy secretary, said: “It’s time everyone in this country who’s got a low wage, a rotten landlord, sky-high bills, or in-work benefits stood up together and said enough is enough.”
Organisers have said tens of thousands have now added their name to the call for arms.
As of 5pm on Monday, the site was working again.
Zarah Sultana, Labour MP for Coventry South, added her voice to the campaign. She said: “Things can’t go on like this: record profits for big businesses, record number of billionaires, record wealth for the top 10 per cent, but life is getting harder for everyone else.”
Labour counterpart Ian Byrme, MP for Liverpool West Derby, is also one of the voices behind Enough is Enough, which has additional backing from CWU, Tribune, the Right to Food Campaign.
Celebrities such as Caitlin Moran also shared their support on Twitter.
A spokesman for the treasury added: “We know that rising prices caused by global challenges are affecting how far people’s incomes go and we have continually taken action to help households by phasing in £37 billion worth of support throughout the year.
“Eight million of the most vulnerable households will see £1,200 direct payments, and everyone will receive £400 over the winter to help with energy bills. The government has also recently accepted the pay recommendations of the independent Pay Review Bodies, providing public sector workers with the highest uplifts in nearly twenty years, targeted towards the lowest paid.
“The UK tax system is progressive, and the £37 billion support package includes a record 5p fuel duty cut to save families £100, reduced national insurance so 70% of workers are better off, and means over a million families keep around an extra £1000 a year thanks to a cut to the Universal Credit taper rate.”
