This deal will allow Ukraine to boost its capabilities, including its essential air defence systems to protect its civilians, cities and infrastructure, which are still suffering indiscriminate attacks as seen this weekend in Kharkiv,” Sánchez told a press conference after the signing.

He said Spain had already pledged to supply Patriot missiles and said it would also send “another batch of Leopard tanks and above all ammunition”.

The Spanish government said the agreement would also include other areas, such as intelligence, training, de-mining, reconstruction and humanitarian assistance.
