A group of activists squatting in a disused office near Trafalgar Square plan to open it to homeless people on Christmas Day.
The group, who call themselves “Love Activists”, say the takeover is a form of “public repossession”.
The building is Grade II listed and was leased by the Royal Bank of Scotland - which was bailed out following the financial crash of 2008 using £46bn of public cash.
It has stood empty for 18 months but is now covered in banners with squatters planning to open it as a public community centre.
They’ll also be dishing out festive meals to homeless people tomorrow.
The group say the protest is against the housing crisis in the capital.
