Crowds gathered in central London as the Trafalgar Square Christmas tree lights were switched on.
The tree was installed earlier in the week.
The Norwegian 🎄in Trafalgar Square is a symbol of friendship between our two countries – past, present & future – a symbol of hope and unity for young & old. Merry Christmas and God Jul! @trafalgartree@CityWestminster@Oslokommune@UKinNorway#MerryChristmaspic.twitter.com/aemNOIZ2J6

Meanwhile, not too far away, Prime Minister Theresa May switched on the Christmas tree lights in Downing Street.
