Bad smells from Mogden sewage works could ruin this autumn's Rugby World Cup, according to a Labour MP.

Ruth Cadbury, MP for Brentford and Isleworth, said unpleasant odours from the Isleworth works could "embarrass" the nation.

During a Commons debate on pollution, she said: "There is a real risk the UK could look rather embarrassing if many matches are spoiled by the stench of sewage floating over the stadium."

She said sewage had seeped into the River Thames close by, but a Thames Water spokesman said the stench was unlikely to cause an issue for the crowds.

A Thames Water spokesman said: "We’re confident rugby fans will not be turned off Twickenham by odour from our works.

"We finished a £140m upgrade in 2013, installing odour-reducing equipment and covers, and have recently refurbished the odour control units.

"We’ll continue to work closely with Twickenham stadium and Hounslow and Richmond councils in the run-up to the big event."
