Mr Cameron saw some of the damage caused to people’s homes and possessions in Mevagissey and Pentewan near St Austell and met members of the emergency services that had dealt with the aftermath of the floods.
The towns were among the areas devastated by heavy rainfall in the early hours of Wednesday.
The PM said:
We’ve got to make sure we get people back in their homes soon. I’ve been incredibly impressed here by the work of the emergency services, and Cornwall Council going door to door helping people out.
It’s incredibly stressful and difficult when you lose your furniture, your possessions, your home - we’ve got to help people get back into their homes as fast as possible and what I’ve seen is communities coming together with emergency services and doing a good job.
Mr Cameron added that he wanted to look at alternative ways of warning communities about flood risk, such as text alerts and changing the weather warning system.
The warnings work according to the river levels whereas actually we ought to maybe be giving people warning when we’re expecting excessive rainfall.
