UK investors were in good spirits on Thursday and the pound hit a four-month high, as official data showed the economy was in better-than-expected health.
The Office for National Statistics said the country’s gross domestic product (GDP) edged up by 0.4% in May, following no growth in April.
Some analysts had been forecasting a rise of 0.2% for the month.
Meanwhile, data published in the US showed that inflation eased to 3% in June across the world’s largest economy.
It continued to raise hopes that the central bank has a lid on unruly price rises and can begin cutting interest rates later this year.
London’s FTSE 100 index was up 29.83 points, or 0.36%, to close at 8,223.34, with utilities firms helping to lift it higher.
And the more UK-focused FTSE 250 was up 1.3% on Thursday amid the positive news on the economy.
In Paris, the Cac 40 closed 0.71% higher and in Frankfurt the Dax was up 0.72%.
In New York, the S&P 500 was down about 0.7% and the Dow Jones up 0.3% by the time European markets closed.
The pound jumped 0.5% against the US dollar at 1.291, its highest level since early March.
Sterling was also up 0.15% against the euro at 1.188.
In company news, shares in Jet2 were given a boost after the holiday company said its profits soared by 43% over the year to the end of March, compared with the previous year.
This was helped by the price of its package holidays jumping by more than a 10th to average £830 over the year, partly from efforts to recoup the impact of cost inflation. Its share price climbed 5%.
It was also a strong session for recruitment firm Hays despite it warning over pressure on its earnings thanks to challenging conditions in Europe.
The company said it had noticed some impact from a period of political uncertainty in the UK and France ahead of general elections.
However, it also revealed cost-cutting measure including trimming back its workforce in recent months. Shares in Hays closed 5% higher.
