Jigsaw puzzle test for Royal Mail

A post office watchdog is testing performance across the region by sending out jigsaws to charities.

Postwatch East of England is sending out a 30-piece jigsaw over four days to nine charities in each of the different postcode areas in the region.

The first to receive all the puzzle pieces will win a cash prize.

"We wanted to test postal deliveries across the region and felt this was a fun way to do so," said Postwatch chairman Dr Charles Winstanley.

He said that postcode areas in the UK have a next day delivery target of 91%.

"We are excited to see which area performs the best and will be waiting for the call from the winning charity," Dr Winstanley added.

All charities will receive a donation for taking part.

Postwatch will begin to send out pieces of the jigsaw to charities from 4 July and the final pieces will be posted on 7 July.
