The bank's forecasts suggest price growth is likely to accelerate in the second half of the year, but some economists have been calling for the bank to cut interest rates for months.
“Inflation is likely to remain above our target for a considerable period of time,” Haskell is expected to say in a speech at King's College London.
This is despite “fairly encouraging signs” that the economy continues to cool.
Financial markets are estimating there is about a 65% chance that interest rates will be cut in August.
“The labor market remains tight and we are concerned it may still be getting worse,” said Haskell, one of the bank's most hawkish policymakers.
“We want to keep interest rates unchanged until we have greater confidence that underlying inflation pressures have subsided sustainably.”
The Governor voted to keep interest rates on hold at the Bank of England's last meeting in June. Today's comments suggest that the Governor is unlikely to choose to cut rates in August, his final meeting of the MPC.
In June the bank voted 7-2 to keep rates unchanged but minutes showed the decision was a “delicate balance”, suggesting an August rate cut is still on the table.
This follows a move by the European Central Bank to cut its key deposit rate from 4% to 3.75% in June.
At the time, European Central Bank President Christine Lagarde said Europe was able to cut interest rates because the inflation outlook had improved “significantly.”
