It was bath-time at the Thames for this giant rubber duck toy which floated down the river to the delight of bemused commuters this morning (Tuesday).

The 50ft toy, which weighs half a ton, set off from West India Dock at the Isle of Dogs at 8.30am and made its way past Canary Wharf before sailing underneath Tower Bridge en route to HMS Belfast.

Former EastEnders star Barbara Windsor launched the duck to publicise the Facebook FUNdation, a Jackpotjoy.com bursery that will provide grants to Brits who come up with daft ideas to encourage people to have more fun.

The actress, who is patron of the website’s Fundation, said: “We thought a giant rubber duck floating down the River Thames was a great way to kick the FUNdation off, and it definitely raised a smile and a chuckle from everyone who saw it.

“After the Queen’s Diamond Jubilee Pageant, the floating Olympic rings and David Beckham jetting into the Olympic opening ceremony, the Thames really has seen it all this year.

“The giant duck was a perfect way to round it all off and it certainly cheered everyone up.”
