Consumer Prices Index (CPI) inflation reached 10.1% last month.
It is the biggest jump in the cost of living since February 1982, when CPI reached 10.4%, according to estimates.
Here is what was happening in the country in 1982:
The unemployment rate stood at 10.4%, the highest it had been for 50 years, with three million (one in eight) people out of work.
The basic rate of income tax was 30%, while the standard rate of VAT was 15%.
Margaret Thatcher’s priorities in the early 1980s included tackling inflation, aiming to reduce the amount of money in circulation by cutting spending and raising indirect taxes.

Mrs Thatcher had been almost three years into her first term as prime minister, but her party was averaging around 31% in the opinion polls, putting it behind Labour (32%) and the Alliance (34%) – a recently formed pact between the Liberal and Social Democratic (SDP) parties.

NHS staff went on a three-day strike over pay in September, with nurses campaigning for a 12% pay rise.
In June, miners in South Wales downed tools in support of health service workers.
In April, the Argentine invasion of the Falkland Islands took place, overpowering 80 Royal Marines and local volunteers.
Over a few months, the British forces would fight back and regain control of the territory.
The conflict cost 255 British lives, while about 650 Argentines died.
In 1982 the Duke of Cambridge was born, while the Duke of York saw frontline action in the Falklands War.
Andrew, the Queen’s second son, flew missions as a Sea King helicopter pilot.
Michael Fagan broke into Buckingham Palace and got inside the Queen’s private chambers while she was still in bed.
The unemployed father of four, 31, spent around 10 minutes talking to the Queen after he climbed over the palace walls and up a drainpipe.
There were just four UK-wide radio stations and three television channels, with Channel 4 launching later in the year.
