June 15 (Reuters) - British fashion retailer Alexon Group Plc said on Tuesday its like-for-like sales for the 19 weeks ended June 12 fell 5.4 percent on lower consumer confidence amid continued economic uncertainty.

The company, whose brands include Ann Harvey, Eastex and Dash, also said its margins were hurt in the period due to increased levels of promotional activity.

The company said recent sales of Ann Harvey were hit by transport distribution issues caused by the volcanic ash cloud, which delayed a key high summer stock package.

Eastex's performance significantly deteriorated around the UK election reflecting low consumer confidence, Alexon said.

The company said it expected the current challenges to continue following the upcoming budget.

"However, subject to a return to normal trading patterns for Eastex over the coming months, we remain on track to deliver a good performance for the full year," the company said in a statement.

Separately, British designer brand Ted Baker (TBK.L) on Tuesday reported an 18 percent rise in its revenue for the 19 week period and said gross margins were in line with expectations.
