Dan was a much-loved colleague who sadly passed away in 2020 from oesophagael cancer. As result of Covid the team could not say farewell or mark his passing. This year we have come up with a number of events which we hope even those of you who had never met him will want to join in. The aim is both to commemorate Dan and to raise money for two charities, Cancer Research UK and Chai Cancer Care, which provided support to him during his illness for which his family was very grateful.
