Figures likely to show the UK economy has enjoyed a third successive quarter of improved growth should give a fresh boost to Chancellor George Osborne today.
Economists predict gross domestic product (GDP) for the three months to the end of September will have increased by 0.8%, after climbing 0.7% in the previous period and 0.4% before that.
Data from the Office for National Statistics look set to provide the second slice of economic cheer this week after separate statistics showing that surging stamp duty revenues helped public borrowing come in £1 billion lower in September than last year.
Growth of 0.8% would be the strongest level recorded for three years and some experts think it could be nearer 1%, amid buoyant survey data from a number of sectors.
However, official figures have been less rosy, showing slowdowns in construction and manufacturing during August.
Meanwhile, retail sales have had a rollercoaster ride, soaring amid the July heatwave, before slumping again in August, then recovering in September.

He said: "Surveys have been very buoyant indeed. However, the official data over the quarter so far have portrayed a slightly less robust picture."
Analysts at Scotiabank predict a reading of close to 1% - lying somewhere between "spectacular" survey data suggesting growth of up to 1.5% and official figures pointing to expansion of as little as 0.5%.
He said domestic demand may have risen by around 1% for the third quarter of 2013 but will have been tempered by disappointing net trade and industrial production figures.
