SPANISH taxi drivers staged an anti-Uber strike yesterday over the ride-hailing app breaking a limit on the number of its cabs.

Normally packed taxi ranks at stations and airports were empty as licensed cabbies refused to pick up passengers, but their unions pledged free rides for the elderly, disabled and pregnant women.

Unions said US firm Uber and Madrid-based Cabify were flouting a law setting a maximum ration of one ride-hailing app cab for every 30 licensed taxis.
