Regarding your leader article “An Invisible Crisis” (4 May, page 3), I agree that the government has abandoned research investment over the past 10 years.

However, in my sector – consulting engineering – we spend an enormous amount of time and money developing new ideas for the construction industry. This is precisely why British engineers are still commissioned to design outstanding projects worldwide.

We would also be world leaders in sustainable solutions if only real financial help came from our politicians.
