Nearly 2,000 different sewage dumps were recorded in the Kenilworth and Southam constituency last year according to Environment Agency data broken down on the 'Top of the Poops' website.

The figures, which include data from Severn Trent and Thames Water, show that there were 20,558 hours of sewage dumps in the area last year - up 771 on the year before.

Of the 1,990 dumps in the constituency, 1,813 were recorded from Severn Trent - the 36 highest number recorded in England and Wales.

The news comes just months after the local MP Sir Jeremy Wright voted against a bill which would have placed a legal duty on water companies to reduce the dumping of raw sewage into rivers.

According to the analysis there were at least 470,000 sewage dumps recorded across the two countries last year.

Severn Trent - which has recently announced a £78million project which will turn part of the River Leam into bathing quality water - said it is committed to improving the region's rivers.

A Severn Trent spokesperson said: "We are absolutely passionate about river quality within our region, and that is why we are consistently recognised as a leading performer in the sector for our environmental credentials, having recently achieved the Environment Agency's highest four star rating for the third year running.

"Storm overflows, which are used in storm conditions to prevent flooding in customer homes and businesses, account for three per cent of rivers not achieving good ecological status.

"Severn Trent is 12 months ahead on each of the targets set out by regulators to improve the quality of its region's rivers.

"We already have monitors on 92 per cent of our sites and we're on track to have 100 per cent installed by December 2022 and as part of our Get River Positive commitments we are on track to reduce the use of storm overflows to an average of 20 per year by 2025 and have pledged that our operations will not be the reason for unhealthy rivers by 2030, based on Environment Agency measures - we're also continuing to invest £100m a year to go even further in improving our region's rivers."
