Labour leader Jeremy Corbyn is set to pledge that he will "stand up to bankers" to "make finance the servants of industry instead of the masters of us all".
Speaking at the EEF, at the Manufacturers' Organisation Conference, he will call for a "fundamental rethink" of the finance industry, saying that deregulated finance has "progressively become more powerful."
He is expected to say deregulated finance's dominance over industry was obvious and destructive and its control of politics "pernicious and undemocratic."
Mr Corbyn will attack a "generation of politicians who thought the City of London could power the whole economy".
He will say: "Out of control financial wizardry and gambling were left barely regulated, while the real economies in once strong industrial areas were put into managed decline.
"For a generation, instead of finance serving industry, politicians have served finance.
"We have seen where that ends: the productive economy, our public services and people's lives being held hostage by a small number of too big to fail banks and casino financial institutions."
Mr Corbyn is also expected to attack the Melrose hostile takeover of GKN, saying that the hostile takeover is an "all too familiar story, like when Kraft took over Cadburys".
He is expected to say a valuable company could be sacrificed so that a few can make a quick buck, and add that Labour would broaden the scope of the 'public interest test' on takeovers, allowing government to intervene to prevent hostile takeovers which destroy our industrial base.
