Sterling edged higher on Wednesday, as a better-than-expected UK service sector survey helped ease worries over the UK economic outlook amid a raft of indicators pointing to slower growth.

The pound rose to nearly 0.3% against the US dollar to 1.248 following the release of the closely-watched Markit/CIPS services purchasing managers' index (PMI) survey, after trading flat for most of the morning.

Versus the euro, sterling edged up by 0.5% to 1.170.

The Chartered Institute of Procurement & Supply's services PMI rose to 55 last month, above economists' expectations of 53.4, and bouncing back from a five-month low of 53.3 in February as client demand strengthened.

"Sterling received a lifeline on Wednesday following March's solid Service PMI figure of 55.00 which boosted some confidence towards the health of the British economy", Lukman Otunuga, a research analyst at foreign exchange broker FXTM, said.

"UK services activity in March has logged its strongest increase this year and such may mitigate the Brexit jitters as concerns momentarily ease over a slowdown in economic momentum."

The FTSE-100 index of leading shares also made gains, ending the day higher by 0.1% or 9.86 points at 7,331.68.
