Boris Johnson was taken to intensive care at St Thomas' Hospital as he continued his battle against coronavirus - but what do we know about the central London facility?
The PM agreed to leave quarantine in Downing Street and go to hospital on Sunday evening after orders from his GP. Having tweeted that he was in good spirits, hours later he was being rushed into ICU last night with his condition worsening.
As one of the UK's best known medical institutions, St Thomas' is located just a short distance from Westminster Bridge - a towering presence over the River Thames.
And medical experts say the hospital has one of the best ICUs in the country, meaning the PM will be getting the best possible care while being treated there.
