Catalonia crisis: Spain could allow referendums, says FM

Spain is considering constitutional changes that could allow its regions to hold referendums on independence in the future, the foreign minister says.

Alfonso Dastis has told the BBC a nationwide vote on the issue could be held.

The move is in recognition of the events in Catalonia, where the regional government was deposed after a unilateral declaration of independence.

Protests were held against the detention of the region's ex-leaders.

Meanwhile, Spain's constitutional court has ruled that the declaration of independence was "unconstitutional and void".
