Britain is at risk, along with Japan and Italy, of being the slowest growing economy among the Group of Seven nations in 2018, Reuters polls of economists showed last week.

Following is a summary of how Britain's economic performance compares with that of other rich nations.

GROWTH

Britain grew more slowly than every other G7 country over the first three quarters of 2017. It looks likely to lag behind both France and Germany in the next few years, according to Reuters polls, the International Monetary Fund and the Organisation for Economic Cooperation and Development.

That would represent a reversal of Britain's outperformance of its peers since the early 1990s, barring a couple of years after the global financial crisis.

Official figures due on Friday are likely to show Britain's economy grew by a quarterly 0.4 percent in the last three months of 2017, repeating the July-September performance, according to a Reuters poll.

That would probably leave average annual growth for 2017 as a whole at around 1.6 percent -- much better than the 1.2 percent Reuters poll forecast from this time last year, but compared with around 2.5 percent for Germany, 2.3 percent for the United States, and 1.8 percent for France.

The Reuters poll pegs growth for this year at around 1.4 percent ahead of Brexit in March 2019, compared with 2.6 percent for the United States, 2.4 percent for Germany, 2.0 percent for France and 1.3 percent for Japan.

EXPORTS

Export volumes from Britain have jumped over the last 18 months but much of the increase is probably linked to the recovery in the global economy, rather than any increase in British competitiveness.

Britain's recent export performance is average compared with other European countries, offering no clear sign of any edge gained from the weak pound.

CONSUMER CONFIDENCE

While consumer morale in the euro zone has hit a 17-1/2-year high, the British public is more sombre, particularly about the economic outlook.

Higher inflation has hurt the spending power of consumers, especially since wages have failed to keep pace with prices.

Consumer confidence in Britain was weaker in December than in all other large European economies, according to European Commission data.

The Thomson Reuters/Ipsos consumer sentiment survey shows Britain was the only G7 country where confidence fell over 2017.

INFLATION

British inflation hit its highest level in nearly six years in November at 3.1 percent, topping rates of consumer price growth in each of the other G7 countries for an eighth month. It edged down to 3.0 percent in December.

The BoE and many economists think inflation has peaked. But surveys of businesses by the Confederation of British Industry and British Chambers of Commerce have suggested inflation pressures could persist.

INVESTMENT

Business investment did not contract as the BoE forecast after the Brexit vote and has grown since mid-2016, albeit at around half its average pace since the financial crisis.

Business surveys suggest Brexit uncertainty has had a tangible impact on companies' investment plans.

Last year JPMorgan said business investment ought to be rising at an annual pace of around 7 percent, given the global growth backdrop, instead of the rates of around 1.5 to 2.5 percent seen during the first three quarters of 2017.

Britain underperformed its peers for investment in the first three quarters of 2017, according to an internationally-comparable measure of gross fixed capital formation (GFCF) that includes spending in businesses, government and dwellings.

GFCF in Britain grew at a slower rate during the first three quarters of 2017 than all of its G7 peers.

However, Martin Beck, economist at Oxford Economics, notes that Britain's business investment performance looks similar to other countries when excluding the oil and gas sector, which in Britain has struggled of late.
