The Parliament's Presiding Officer, Ken Macintosh, said: "Our focus has always been for this Parliament to be open and accessible for all and what better opportunity to open our doors than for our 20th anniversary celebrations.

"There truly is something for everyone as we celebrate our birthday and play host to the best of Scottish culture.

"There's music, dance, food, games, talks, birds of prey and you can even sit in my chair. And best of all it's free.

"So come help us toast 20 years of your Parliament for what promises to be a great day out for all."
