The British economy has outperformed all others in the G7 group of developed nations over the past year, an international think tank has said.

The UK grew by 2.3 per cent in the year to the end of September, outpacing all other members of the group and the wider European Union.

The data collated by the OECD is a further signal that business uncertainty over the Brexit vote in June is not yet hitting the economy despite the doom-laden predictions made by the Remain campaign ahead of the poll.

The robust economic growth comes after strong employment figures, lower than expected inflation data and surging retail figures from the high street.

Chancellor Philip Hammond will be boosted by the figures as he prepares to deliver his first autumn statement on Wednesday.

Revealing its quarterly analysis today, the OECD said: 'Real growth of gross domestic product (GDP) in the OECD area picked up markedly to 0.6 per cent in the third quarter of 2016, compared with 0.3 per cent in the previous quarter, according to provisional estimates.

'Growth accelerated in most Major Seven economies in the third quarter of 2016, with the exception of the United Kingdom and Germany, where growth slowed to 0.5 per cent and 0.2 per cent, respectively, compared with 0.7 per cent and 0.4 per cent in the previous quarter.

'In the United States, growth accelerated to 0.7 per cent in the third quarter of 2016, following a rate of 0.4 per cent in the previous quarter.

'Growth also picked up in Japan, to 0.5 per cent, compared with 0.2 per cent in the previous quarter, and in Italy and France (to 0.3 per cent and 0.2 per cent, respectively, compared with 0.0 per cent and minus 0.1 per cent in the previous quarter).

'In the European Union and in the euro area, growth was stable at 0.4 per cent and 0.3 per cent, respectively.

'Year-on-year GDP growth for the OECD area was 1.7 per cent in the third quarter of 2016, marginally up from 1.6 per cent in the previous quarter.

'Among Major Seven economies, the United Kingdom (2.3 per cent) and Germany (1.7 per cent) recorded the highest annual growth rates, while Japan registered the lowest (0.8 per cent).'

The figures will be a boost for Chancellor Philip Hammond (left, alongside shadow chancellor John McDonnell on the BBC yesterday) as he prepares for his first Autumn Statement on Wednesday

Mr Hammond is poised to announce £1.3 billion for improvements on Britain's roads among a raft of infrastructure investment - although unlike Mr Osborne he will leave it to individual ministers to announce the individual projects.

Despite abandoning the former Chancellor's plan for a budget surplus by 2020, Mr Hammond is set to unveil a new 'flexible' fiscal framework with a rolling target for eliminating the deficit.

Other measures in the package will include banning pension cold calls which can leave people open to scams which trick them out of their life savings and is reportedly expected to approve another freeze in fuel duty until April 2018.

Mr Hammond could also crack down on staff perks like gym memberships and mobile phone contracts which are offered to workers willing to forgo part of their salaries in return in an effort to boost tax revenues, according to reports.
