UK inflation just hit its highest level in more than 2 years
The ONS said that the UK's consumer price index - the key measure of inflation - was 1.2%, up from 0.9% in October, and ahead of the 1.1% forecasted by economists.
Core inflation figures, which strip out volatile goods like oil and food, rose to 1.4% in the month, up from 1.2% at the previous reading, and ahead of the predicted 1.3%.
Here is how November's data looks like as part of the long-term trend (note the drop from September):
Despite increasing, inflation remains well below the long-term trend - as the chart shows, inflation was more than 5% as recently as 2011 - however after two years of negligible price growth, 1.2% is still substantial.
Prior to the last few months, inflation stayed between -0.1% and 0.1% for 10 months due to a collapse in oil prices and a supermarket price war that led to slashed prices.
Prices had started to pick up following the Bank of England's decision to cut interest rates in the aftermath of the UK's vote to leave the European Union, and the fall in the value of the pound.
Expectations remain that inflation will jump sharply in the coming months as the effects of the weaker pound - which has fallen roughly 14% since the Brexit vote, and sits at a 31-year low against the dollar - trickle into the real economy, pushing up the price of goods.
As a result, the Bank of England has said that it is willing to tolerate an overshoot in inflation beyond its 2% target over the coming months in order to protect jobs.
Inflation will more than double to overshoot the Bank of England's 2% inflation target in 2018, driven up by a falling currency, the central bank said in its quarterly Inflation Report in November.
"In the central projection, inflation rises from its current level of 1% to around 2.75% in 2018, before falling back gradually over 2019 to reach 2.5% in three years' time," the Bank said.
Concerns about an increase in the price of goods and services in the UK since the Brexit vote came sharply into focus for many UK consumers in October, when Britain's largest supermarket Tesco briefly stopped stocking products made by Unilever, including Marmite, Colman's Mustard, and Hellmann's mayonnaise.
Those fears then returned when it was announced that Toblerone would make its bars smaller in the UK in response to the increasing price of raw materials post-Brexit.
