Around 400 people are expected to descend on Princes Risborough on Wednesday to attend a funeral in the town. 

There is expected to be heavy congestion on roads in the town as the funeral attendees try to get into Risborough and park on May 22. 

Transport for Bucks is urging drivers to avoid the area if possible and look for other routes, adding that all the "relevant authorities" are aware of the plans. 

Although there will be no road closures, the congestion is expected to last from around 11am to 2.30pm.
