Alison Hammond was forced to step in for the pair

This Morning presenters Phillip Schofield and Holly Willoughby were left stranded on the River Thames after the boat they were in appeared to run out of fuel.

The duo were live in central London touring HMS Belfast on a speedboat during Thursday’s edition of the ITV show.

After the boat ran out of petrol on its way back to shore, they were left in a fit of giggles while Alison Hammond stepped in to cover for them back in the studio.

They were celebrating 80 years since the launch of the warship and were expected to be back on dry land following an advert break.

Holly asked: “Have we got a leak?,” before Phillip was drenched by a wave and added: “Seriously, Alison might have to do the rest of the show.”

Alison told viewers: “We might have to send someone up there to rescue Phil and Holly,” before interviewing actress Amanda Redman.

Eventually the pair were rescued and had to film the rest of the show a little damp.

Viewers on Twitter were entertained by the ordeal, labelling it “hilarious”.
