Can you solve the GCHQ Christmas challenge?

Greggs and donuts: BBC goes inside GCHQ's secretive base

Latin dancing, Indian butter, and American soldiers are among the hints featured in this year's cryptic Christmas challenge from the UK’s national spy agency, GCHQ.

The annual brainteaser is presented in the form of a Christmas card, sent by Director Anne Keast-Butler.

This year’s puzzle invites participants to decipher the names of UK landmarks, testing a range of skills such as codebreaking, mathematics, and lateral thinking.

Described by GCHQ as deceptively challenging, the tasks demand creativity and determination.

For those seeking an even greater test, the 2024 card includes hidden layers within the code, offering additional elements to decode.
