Spain's Gambling Ad Curbs Facing Challenge

• Trade group calls restrictions "disproportionate"
• Group argues clubs will suffer 
• Minister cites "social alarm" 

Gambling advertising will be restricted to the early-morning hours in Spain and sports clubs will need to end gambling sponsorship contracts at the end of the current season as the Council of Ministers approved a controversial royal decree on Tuesday.

The restrictions were denounced by Spain's biggest online gambling trade group, Jdigital, as "discriminatory, unfair and disproportionate".
