Deputy Prime Minister Nick Clegg has warned that energy companies risk "exhausting" public confidence if they keep raising bills.
Speaking on The Agenda with Tom Bradby, he said:
In any developed capitalist economy you can't operate in a vacuum ... Profit is what drives a lot of these things but you can't operate without public consent ...
I think they do need to be very careful that they don't sort of exhaust public consent and confidence that they're doing the right thing by these very, very significant price hikes.
