Deidre is attending the switch on of the 'Luminations of Love' light display in St Andrew's Square.
The 'Glow Gold' campaign has seen almost 200 famous landmarks and buildings sign up to light their façade in gold in its inaugural year, including Edinburgh Castle, the National Galleries and St Andrew's House in Edinburgh.
The campaign was started by Edinburgh parents, including North and Leith constituent Pam Neilson who lost her 3 year old son Kai to cancer in January.
"It's a rare enough sight to see Edinburgh basking in a golden glow in the summer, let alone September, but it's even more special when it's to show support for children with cancer.
"Pam Neilson sadly lost her son Kai to cancer but she is building a phenomenal legacy for him with this positive campaign.
"Pam and the team of parents behind 'Glow Gold' are working their socks off to make a difference to other families who are affected by childhood cancer. Too many people aren't aware of the early symptoms, nor how common it is, so 'Glow Gold' has set out to change that.
"This is 'parent power' in action, a grassroots campaign which is already having a global impact. I'm impressed by how many major landmarks are lighting up not just in the UK but around the world.
"Here in Edinburgh the Castle, the National Galleries and St Andrew's House are amongst the city landmarks which are glowing gold - and it's brilliant to see Lothian Buses backing the campaign by taking kids around the city on a shiny 'glow gold' bus.
"We can all make a difference by wearing gold ribbons, putting up posters and showing our support for kids with cancer. I'll certainly make sure my constituency office has information and posters on display this month to help spread the word.
"Well done to everyone behind 'Glow Gold' and I look forward to doing what I can to help this very worthwhile campaign."
