Sleep in the Park raises millions for homeless
More than 8,000 people "slept rough" in temperatures as low as -7C in an event to tackle homelessness.
Each participant had to raise at least £100 to take part in Sleep in the Park, in Edinburgh's Princes Street Gardens.
The event, said by organisers to be the biggest ever charity sleepout, has already raised £3.6m.
