Prime Minister says the water outage crisis in Kent and Sussex is 'totally unacceptable'
Ministers are holding emergency meetings about the crisis
Ministers are holding emergency daily meetings as 17,000 properties remain without drinking water across Kent and Sussex.
South East Water (SEW) has blamed the latest supply failure, which comes after a similar incident in December, on Storm Goretti causing burst pipes and power cuts.
Water has been returned to 8,000 customers across the two counties, but thousands of people are now enduring a fifth day without water.
Liberal Democrat leader Sir Ed Davey has called for SEW to be stripped of its licence for failing "over and over again", during an exchange during Prime Minister's Questions on Wednesday.
He said: "Families, pensioners, schools, care homes and businesses without any water since Saturday, and the water company bosses involved now stand accused of misleading Parliament over their failures. South East Water keeps failing its customers over and over again. So will the Government immediately strip them of their licence?"
Sir Keir replied that the situation is "totally unacceptable".
He said: "He will want to know that ministers have chaired daily emergency meetings to hold the company to account to deliver on the change that's urgently needed at the moment in all the areas that he mentioned.
"We've also doubled the compensation rates for individuals and businesses and we're absolutely clear the company must urgently invest in infrastructure and we'll publish the water White Paper in due course."
South East Water's incident manager Matthew Dean said: "Once again, we are very sorry to all our customers who have been affected.
"We know and understand how difficult going without water for such a long period of time is and how difficult it makes everyday life."
Bottled water stations remain in place in Tunbridge Wells, East Grinstead and Maidstone, and location details can be found on SEW's website.
