The frequency of extreme rainfall in the UK may be increasing, according to analysis by the Met Office.
Statistics show that days of particularly heavy rainfall have become more common since 1960.
The analysis is still preliminary, but the apparent trend mirrors increases in extreme rain seen in other parts of the world.
It comes as the Met Office prepares to reveal whether 2012 was the wettest year on record in the UK.
The study into extreme rain is based on statistics from the National Climate Information Centre, the UK's official climate record.
