Margot James is supporting the CLIC Sargent charity by sending a Tweet-length message to the Edge of Space, and encouraging others to do the same.
CLIC Sargent is the UK’s leading cancer charity for children and young people, and works to provide a range of support to those diagnosed with cancer.
Each message costs just £2.50 and Margot’s reads ‘If you afford it please donate to CLIC Sargent, which does very worthwhile work supporting children and young people with cancer’.
