George W Bush has been criticised for his behaviour at the Dallas memorial after he was caught on camera dancing along to a sombre hymn.

The ceremony was held yesterday in honour of the five police officers killed in the shootings on July 7.

Holding Michelle Obama’s hand on one side – and his wife Laura’s hand on the other – the former US President was captured by cameras as he swayed during a choir’s performance of ‘The Battle Hymn of the Republic’.

He continuously smiles at the pair while waving their arms around, as Michelle attempts to stand still.
