MORE than 160,000 people have staged a demonstration in Barcelona calling for a unified Spain.

The march, backed by the PP, called for Cataluna to remain under the control of Spain’s central government.

The rally enjoyed a significant increase in the turnout compared to last year, when 100,000 people took to the streets.

But the movement remains in the minority, with political parties supporting the cause representing just 20% of the seats in the Catalan parliament.

It also comes a month after 1.5 million people staged a similar protest calling for Catalan independence.
