Published by Zeb BhamForeign exchange traders are this morning (April 19th) awaiting the publication of first-quarter gross domestic product data, with expectations of 0.4 per cent growth during the period.Positive figures are expected to provide a fillip for Gordon Brown's election campaign, while evidence of a double-dip recession may prove disastrous for the incumbent.The latest YouGov poll for the Sun places Gordon Brown in third place with 26 per cent, David Cameron in second place at 32 per cent and Nick Clegg up one percentage in poll position in the race to Number 10.Speaking to the Telegraph, Howard Archer, chief economist at HIS Global Insight, said that expectations of growth in the upcoming figures are far from assured."The anticipation over the release is heightened by the fact that there is massive uncertainty surrounding the outcome due to the serious hit to economic activity in January coming from the arctic weather conditions," he commented.For more information on foreign exchange treasury services and risk management, visit our Corporate FX site
