The UK's economy was on the up before the Brexit vote

But all post-referendum indicators show that the vote has caused a slowdown across Britain...

The UK economy grew by 0.6% in the second quarter of the year - more than expected in the run-up to the EU referendum.

Analysis of the country's gross domestic product (GDP) by the Office for National Statistics (ONS) during the April to June period showed a surprise acceleration in output - given jitters over the Brexit vote's outcome.

Economists had expected a similar performance to that in the first quarter when growth was measured at 0.4% though it was clear growth was at its strongest in April.

The ONS charted the biggest jump in quarterly industrial production since 1999 over the three months with growth of 2.1%. The sector had been in decline over the previous quarter.

Construction output was determined to have fallen by 0.4% - down from a 0.3% decline in the first quarter.

The service sector, which is responsible for more than three-quarters of total UK output, slowed slightly with growth of 0.5%.

The ONS stressed that the GDP figure was an initial estimate and subject to revision.

Chancellor of the Exchequer, Philip Hammond, said: "Today's GDP figures show that the fundamentals of the British economy are strong.. so it is clear we enter our negotiations to leave the EU from a position of economic strength."

But he warned tougher times lay ahead, adding: "Those negotiations will signal the beginning of a period of adjustment, but I am confident we have the tools to manage the challenges ahead, and, along with the Bank of England, this

Government will take whatever action is necessary to support our economy and maintain business and consumer confidence."

The latest economic data suggests Mr Hammond is right to be cautious.

A flash survey of purchasing managers released last week suggested economic growth had slumped at its fastest rate since the financial crisis.

Scott Bowman, UK economist at Capital Economics, said: "The (April-June) quarterly expansion was completely driven by activity in April, with the output indices implying a 0.9% monthly expansion.

"In contrast, these indices suggest GDP fell in May and ONS initial estimates for June imply that activity was flat in June.

"This sets a poor base for growth in the third quarter."

The new government in London has signalled it is ready to inject more money into the economy to help boost activity while the Bank of England has hinted at a possible cut to interest rates at its meeting next week.

One policymaker, Martin Weale, said earlier this week he was now in favour of further support for the economy - given the readings in the flash PMI survey.
