Inflation in the UK saw a shock fall in October

Inflation in the UK witnessed a shock fall in October, according to the latest data released by the Office for National Statistics on Tuesday.

Core inflation figures, which strip out volatile goods like oil and food, fell to 1.2% in the month, down from 1.5% at the previous reading.
