Spain’s elections Sunday will be a battle between two leftist and two rightist parties that are teaming up to form potential coalitions.

The leader of Spain’s main opposition party, Pablo Casado, will remain in charge of the Popular Party until early April, when party members are expected to choose a new leadership.

The leader of Spain’s main opposition party is set to meet fellow conservative heavyweights with his future at risk amid an ugly clash with a Popular Party rival.

Months of simmering tensions within Spain’s main opposition party has come to a head with an exchange of ‘friendly fire’ between the conservatives’ national leadership and the regional chief of Madrid, a rising star in the Popular Party.

Opposition leader Pablo Casado announced Thursday that the 88 lawmakers of his conservative Popular Party would vote against Vox's motion and lambasted the far-right party for “wasting everybody's time” with the debate as the country grapples with a resurgence of the virus. Vox leader Santiago Abascal responded by saying that Casado's position was showing the true colors of the Popular Party.

(AP Photo/Manu Fernandez)MADRID – A Madrid court on Thursday struck down a national government order that imposed a partial lockdown in the Spanish capital and its suburbs, siding with regional officials who had resisted stricter measures against one of Europe’s most worrying virus clusters. It also left 4.8 million residents in Madrid and nine suburban towns wondering whether it was appropriate to go away on a long weekend extended by Monday’s national day celebration. Casado also called for the health minister to step down for promoting measures that he claimed politically targeted the Madrid region. Experts say numbers in all countries understate the true toll of the virus due to limited testing, missed cases, government concealment and other factors.
