“We are in the process of coordinating with other countries,” he said during an interview with private Spanish television station La Sexta when asked if this step would be taken on Tuesday as announced by EU foreign policy chief Josep Borrell.

Sanchez said in March that Spain and Ireland, along with Slovenia and Malta had agreed to take the first steps towards recognition of a Palestinian state alongside Israel, seeing a two-state solution as essential for lasting peace.

Borrell told Spanish public radio last week that Spain, Ireland and Slovenia planned to symbolically recognise a Palestinian state on May 21, saying he had been given this date by Spanish Foreign Minister José Manuel Albares.

Ireland’s Foreign Minister Micheal Martin said Tuesday that Dublin was certain to recognise Palestinian statehood by the end of the month but the “specific date is still fluid”.

So far, 137 of the 193 UN member states have recognised a Palestinian state, according to figures provided by the West Bank-based Palestinian Authority.

Despite the growing number of EU countries in favour of such a move, neither France nor Germany support the idea. Western powers have long argued such recognition should only happen as part of a negotiated peace with Israel.
