Earlier UK data showed the unemployment rate rose to 4.4% in the three weeks ending in December from 4.3%, while average wages rose 2.5% in line with expectations.
UK jobless claims fell by 7.2 thousand, compared to a 6.2K increase in the previous reading, while analysts expected a 2.3K rise.
Net public borrowing rose to 11.6 billion pounds, compared to a surplus of 0.3 billion in January.
Otherwise, earlier US data showed positive flash readings for both manufacturing and services PMIs, while existing home sales fell unexpectedly in January.
