Rishi Sunak called Money Saving Expert Martin Lewis for tips before announcing a £15bn cost-of-living package.
The Chancellor reached out to the personal finance specialist in May, days before announcing £400 off all energy bills, £650 for people on benefits and £150 for the disabled this winter.
Mr Lewis had previously confirmed the conversation - but was asked about it in more detail today at the Future of Britain conference, hosted by the Tony Blair Institute.
