But it still stands that it is a local planning decision to allow building on floodplains to go ahead, and that is very much an MHCLG agenda.

I want to talk about the reservoir issue that the hon. Gentleman raised. Many people are suggesting that that provides a simple answer to some of our flooding issues and also our water supply issue, but of course they are very complex issues involving a range of stakeholders and they have to be considered in relation to how reservoirs might be managed and operated throughout the year. On that, I must give assurances that flood and coastal erosion risk management is a big Government priority now, with £2.6 billion already devoted to this area in the last spending round up to 2021 and the recent announcement, to be confirmed in this week’s Budget, of funding for flood defences of £5.2 billion. That will be helping a further 2,000 new flood and coastal defence schemes and better protect 336,000 properties across the country.

There are of course reservoirs at the moment that are used for flood risk management. The Environment Agency operates more than 200 reservoirs around the country, especially for flood attenuation. That is their purpose in life and the amount of water in them during non-flood conditions is kept deliberately low in order to maximise the storage available during high rainfall and storm events. Many of those reservoirs have been operated this winter, and, in combination with other flood defence measures in the catchment, have provided protection to a great many people.
