Giving evidence at a Treasury select committee hearing, Dr. Mark Carney claimed families were US$1,200 (£900) worse off following the European Union referendum held in the UK in 2016.
"Real household incomes are about $1,200 (£900) per household lower than we forecast in May of 2016, which is a lot of money," Dr. Carney said.
The Bank of England's governor also said Britain's economy was two percent smaller than predicted before the EU referendum was held in 2016.
