While the new price cap will be unveiled in the last week of August it is expected that it will bring significant increases to the energy bills.
In an interview with Times Radio, Business Secretary Kwasi Kwarteng said: “The only way that we can deal with the immediate issue is through an emergency budget, through interventions and that’s going to happen.
“But of course, until we have a new Prime Minister, which is only in four weeks’ time now, we have to wait for the new Prime Minister and the new Chancellor as they are going to have to work together on this, to get a support package across.”
By that time, energy suppliers will already have “crystalised their policies and started communicating to customers about a direct debit rise.”
Asked whether he knew where Boris Johnson was and what the Prime Minister was saying about the energy crisis, Mr Kwarteng said “I don’t know where Boris is, but I am in constant contact with him.
