Boris Johnson was met with shouts of “traitor” as he arrived in Worcestershire on Sunday to see efforts to tackle flooding.
The PM arrived on the banks of the River Severn in Bewdley on Sunday afternoon and was taken to view flood defences by Environment Agency staff.
Some onlookers shouted “traitor” at Johnson, who has faced criticism for failing to visit flood-hit communities sooner.
Bewdley has been among the worst-hit areas in England following the wettest February on record.
Johnson received a mixed reception as he walked through Bewdley town centre.
While a number of teenagers asked him to stop for a selfie on the bridge, and he happily obliged with a smile and a thumbs up, as he walked back on to the river bank, one man shouted “do your f****** job”.
The PM was then given a demonstration of how the barriers work on Severn Side North, and told affected residents he would “get Bewdley done”.
He said he was “so sorry to hear it” when he heard homes had been overwhelmed by as much as 2ft of water.
The PM spoke to the Environment Agency and said they discussed “what permanent defences can we put in and what’s the business case”.
He added: “What we’re doing is we are doubling the funding for flood defences to £5.2 billion and we’re also going to be looking at all the things we can do upstream.”
