About 20,000 people expected at soapbox race

About 20,000 people are expected to attend a charity soapbox race on Sunday.
The organisers of the Great Dunmow Soapbox Race in Essex have promised an "action-packed day of homemade racers, wild costumes and roaring crowds".
The event has raised more than £150,000 since its inaugural race in 2018.
For the second year running, a high-powered foam cannon will blast bubbles on to the track.
Lead organiser Oliver Wyatt said: "We have been blown away by the and generosity of spectators from previous events, and we hope to make a real difference to local charities as a result.
"People come from all over the world to take part with their homemade karts and there are bars, stalls and entertainment for the whole family to enjoy. "

The soapbox racers will speed down Braintree Road near the centre of the town - a stretch of road that is 300m long (984ft).
The race is due to begin at 10:30 BST.
