The British Heart Foundation has set up an all-party parliamentary group on heart disease to raise the profile of Britain's single biggest killer within Westminster.
A total of 155 MPs and peers have joined the group, which held its inaugural meeting earlier this month.
There are already 240 such groups within Westminster on issues including diabetes and kidney problems. The absence of a group for heart disease was a "glaring gap", said a charity spokeswoman. It plans to work with other all-party medical groups such as the group on cancer because the two diseases share common risk factors.
The group took six months to set up. The foundation conducted a survey of MPs and peers to see if there was enough interest to start up a group, which must have a minimum of 20 members. The charity also plans to start educating MPs about their own health and preventative strategies.
