The Irish Cancer Society's biggest fundraiser is back in full bloom this year with the aim of raising 4 million euro for the charity.

Daffodil Day first launched back in 1988 and is now responsible for raising around 20 per cent of the charity's income.

Volunteers will be out in force across the country.

Averil Power, chief executive of the Irish Cancer Society, says there is increased demand for many of their services.
