Stephen McPartland, MP for Stevenage, joined as MBDA employees raised thousands of pounds for Macmillan Cancer Support at the Lister Hospital by having their heads shaved.
Hairdressing students from North Hertfordshire College helped out by shaving the heads of a total of 37 employees.
The idea to raise money for the Macmillan charity in this way was to show support for one of their work colleagues at MBDA who suffered hair loss as a result of chemotherapy treatment.
