Neighbours on lockdown in Spain placed a birthday cake outside the home of a woman turning 80 before erupting into a chorus of 'Happy Birthday' in heartwarming footage.

The clip, filmed in Lavapies in Madrid, captures a kindhearted man as he knocks on the door of Charo, who lives alone in the Spanish capital.

He calls out his neighbour's name before the emotional 80-year-old opens the door to discover a cake placed on a small table outside her front door.

As Charo then steps out of her apartment, residents from the neighbourhood burst into a rendition of 'Happy Birthday' from their apartment windows.

Charo's birthday had fallen days after the Spanish government announced the entire country would go into lockdown in drastic measures to prevent the spread of coronavirus.

Around 11,400 people have tested positive for the virus in Spain, with 499 deaths reported as a result of the pandemic.

Some 4,165 of these cases have been confirmed in Madrid, with 213 people reported dead in the capital alone.

As the clip continues, Charo struggles to hold back tears as she retreats for a moment into her apartment's doorway.

She then rushes back over to the hallway window to wave at her neighbours as they sing, before thanking them with a round of applause.

It was reported there is a 'strong sense of community' in her neighbourhood because some of the residents are in danger of being evicted over fears their properties may be unsafe.

One neighbour, Nacho, explained Charo is 'going through a tough time' and the 'least we could do as neighbours is support each other'.

He said: 'Charo is 80 years old, she is a person at risk. We do not know what is going on with our homes, but she is lucky because she has a contract for one more year. However, others have been evicted.

'She is going through a tough time and the least we could do as neighbours is support each other, especially where vulnerable people are concerned.'

Spanish residents have been asked to only leave their homes for work or to visit the supermarket, pharmacy, bank or medical centre.

Residents have also been told they can leave their houses to care for elderly loved ones or those dependent on others, but even then they should keep a safe distance.

Dog owners are allowed to leave their homes to walk their pets, but only one person at a time.
