Britain fell into a deep recession five years ago and has endured a bumpy ride ever since, falling at its lowest point to 6% below its peak.
The economy has struggled to recover ever since.
A recession is two or more consecutive quarters of negative national economic growth. A quarter is a period of three months.
The economy shrank for the final three quarters of 2008 and the first two of 2009 as shown in the graph above in the blue bars which dip below the line.
Although the initial recession then came to an end, subsequent growth was sluggish and punctuated by setbacks.
Plunging business investment then triggered the beginning of the second dip at the end of 2011, the start of three successive quarters of decline that stretched into the first half of last year.
Official figures revealed Britain dodged a much-feared triple-dip recession with growth of 0.3% in the first three months of the year.
Today's news that a triple dip recession has been averted means very little in economic terms, but politically it is critical.
The latest GDP figures show Britain has avoided another recession, but the long-term picture is of an economy that remains resolutely flat.
