I'm part of an WhatsApp quiz group. We've been given 10 clues about a town and we have to work it out. All I know is its in the UK.

The clues are.

1. Trumpton
2. River Number
3. Pepper Pot
4. Sunshine
5. Ham
6. Rude Road Name
7. Folk, Jazz, Blues
8. Alpha 21
9. Floods

10. Prime Ministers Ex Wife

Any ideas?

The only one I can get is river number- severn?

The number must be the Severn?

Lewes?

Ex wife is Marina so a town on the coast?

Upton upon Severn.

Alpha 21 = U. There is a cupola known as the Pepperpot there.

They also have folk, blues and jazz festivals.

ThePepper Pot is in Brighton though.

I was going to say Tewkesbury. Floods, River Severn, the flood plain is called the Ham, has a marina....

There's is also a tower known as the Pepperpot in Upton-upon-Severn.
