The group's benchmark EBIT rose by 5% to $581m and benchmark pre-tax profits were up 4% at $541m.

Chief executive Brian Cassin said: 'We have started the year well and are on course to deliver stronger organic revenue growth as we move through the year.
'We are now consistently delivering strong growth in our B2B activities and anticipate a further moderation in the decline of Consumer Services as new product launches take root.
'The benefits of investments in our technology transformation, our One Experian approach and exciting new product innovations are visible in our results and we are laying foundations for strengthening performance as we move forward.
'Looking ahead, we continue to expect good levels of growth for the year, with organic revenue growth in the mid-single digit range and stable margins as we invest in our operations and growth initiatives.
'We also continue to expect further progress in Benchmark earnings per share.'
