Thousands of people are expected to march through the street of Edinburgh today in support of Scottish independence.
The All Under One Banner (AUOB) rally starts at Holyrood Park at 1pm and will snake through the city before finishing at The Meadows.
A similar event last year saw 20,000 people attend, however that number is expected to be higher today.
With thousands descending on the capital transport chiefs have warned about potential disruption throughout the course of the day.
The following roads will be closed between 12pm and 6.30pm: Queen’s Drive, Horse Wynd, Canongate, New Street, High Street, Lawnmarket, George IV Bridge, Forrest Road, Potterrow, Teviot Place and Lauriston Place.
Meanwhile, Scotrail has advised people to plan their journey in advance as services in and out the city will be busy due to a number of events.
Scotrail tweeted: “Services to and from #Edinburgh are expected to be very busy today due to a number of events taking place, all available units will be in use.
“Please #PlanAhead, allow extra time to travel and buy your ticket before boarding the train.”
SNP MPs and celebrities are lined up to speak at the event, including Joanna Cherry, comedian Janey Godley, broadcaster Hardeep Singh Kohli, and former MSP Tommy Sheridan.
