Higher air fares have contributed to a bigger-than-expected rise in inflation.

Official figures show the rate at which prices are going up increased from 3-point-6, to 3-point-8-percent last month.

A separate measure’s suggested a potential 5-point-8-percent hike to the cost of season tickets on the trains in England next year.

Lib Dem MP for Wimbledon, Paul Kohler, wants to see fares frozen.

A decision is expected later this year.
