Thousands of people in Spain are protesting against the government's handling of the coronavirus outbreak.
The far-right Vox party urged supporters to drive through major cities without leaving their vehicles in order to maintain social distancing.
Protesters in the capital, Madrid, drove in convoy and waved Spanish flags as they called for socialist Prime Minister Pedro Sánchez to resign.
Spain imposed some of the tightest restrictions in Europe on 14 March.
It has eased restrictions in recent weeks, but Madrid and Barcelona have remained under tight lockdown due to their more severe outbreaks of Covid-19.
The country's two-month lockdown has seen hotels, bars and restaurants all close as well as beaches and other outdoor attractions.
The government says this has allowed it to get the outbreak under control, and the daily death toll has been gradually declining.
But, on Saturday, far-right protesters called for the lockdown to be lifted entirely owing to its impact on jobs and the economy.
Almost one million jobs were lost in March alone, and forecasts suggest the Spanish economy will contract by up to 12% this year as a result of the pandemic.
The demonstrators called for both Mr Sanchez and Deputy Prime Minister Pablo Iglesias, who heads the left-wing Podemos party, to step down over their handling of the crisis.
"It is time to make a big noise against the government of unemployment and misery that has abandoned our self-employed and workers," the opposition Vox party said in a statement.
