Leading figures from UK public life gathered at St Paul’s Cathedral today for a service of thanksgiving in honour of the Queen’s Diamond Jubilee.

But the Duke of Edinburgh will be missing as he is being treated in hospital for a bladder infection.

It was announced this morning (Tuesday) that the Queen will give a message of thanks for this weekend’s Diamond Jubilee celebrations in a special address broadcast this evening.

The address, lasting just over two minutes, was recorded in the Presence Room in Buckingham Palace yesterday before the Jubilee Concert.

It will be transmitted on television and radio at 6pm today in the UK and across the Commonwealth, and will also be available on the Royal Channel on YouTube.
