Valentine’s Day 2015 is going to be extra special. Why? Because it falls on a Saturday, meaning no work the next day, meaning extra scope for late-night fun (and cosy lie-ins). Here are the parties that London has to offer this February 14, with plenty to do for loved-up couples, embittered singles and anyone looking to segue messily from the latter to the former. Have fun out there, and don’t do anything we wouldn’t do!
