King Felipe VI and Queen Letizia are joined by their princess daughters for the country's national day in Madrid - as thousands of Catalans march in Barcelona

King Felipe VI was joined by Queen Letizia and Princesses Leonor, 11 and Sofía, 10, at the annual military parade in Madrid - while 300 miles away, thousands of Catalan 'remainers' marched in Barcelona (inset). The holiday is known as Dia de la Hispanidad and celebrates Christopher Columbus' arrival in the New World; it is also Spain's armed forces day. But today's celebrations come amid one of the country's biggest crises ever as its powerful northeastern region of Catalonia threatens to break away from Spain.
