Services revenue increased by 6% on a reported basis and 4% in constant currency. Supply Chain revenue increased by 5% on a reported basis and 2% in constant currency. Computacenter said it expects its main markets in Britain and Germany to benefit from order wins and margin improvements in 2014."The Group enters 2014 expecting to make further progress in our performance during the year. The momentum we have built up over the last three years in the UK should be maintained due to recent Services wins, and the German Services margin improvement has further to run."While we would expect an improvement in our French performance, we will resist the temptation of improving the short-term and not fixing it fundamentally to improve the long-term," it said.
