TORY ministers are condemning every British household to an energy bill jump of at least £67 a month from Saturday, campaigners are warning on “April Fuels Day.”

The crippling increase — prompted by the government’s move to withdraw £400 in financial help to every family by scrapping the Energy Bills Support Scheme — has prompted activists to organise a mass lobby of MPs at more than 70 locations nationwide on Saturday.

The move, which Downing Street argues is justified as wholesale prices start to fall, coincides with new figures from the Warm This Winter campaign that reveal nearly three in 10 Brits are already in debt to mega-rich electricity and gas companies even before the latest price hike.
