The October 29 disaster, which destroyed infrastructure, wrecked buildings and flooded fields, sparked outrage from authorities over their alleged mismanagement, with one minister admitting that many of the deaths were "preventable".
Given Sanchez's participation in this week's G20 summit in Brazil, that appearance could take place on November 27th, the Moncloa Palace added.
Political tensions over dealing with Spain's worst disaster in a generation have risen, with the centre-left central government trading accusations with the right-wing administration in Valencia, the worst-hit region.
Valencia's regional authorities were heavily criticised for being slow to react to the weather warning, for taking too long to ask people to stay indoors, and for delaying aid.
Meanwhile, the opposition has criticised the Spanish government for failing to take responsibility for managing the emergency, accusing it of being slow to provide funds for the rescue operation for political reasons.
The socialist government rejects the accusation, placing responsibility for dealing with the floods in the hands of local authorities.
On 15th of November, Valencia's right-wing governor Carlos Mazon admitted to "mistakes" in dealing with the floods, and two days later Transport Minister Oscar Puente said that "a significant number of deaths could have been avoided".
"Lives could have been saved with a little more caution, waiting and prudence," he told La Vanguardia newspaper, without giving further details. | BGNES
