David Cameron will represent the UK Government at the event to mark the 100th anniversary of the Battle of Jutland, alongside members of the Scottish Government, the Royal Family and descendants of those killed.

The Islington MP is expected to be on holiday next week, while Westminster takes a short recess.

A service will be held at St. Magnus Cathedral, Kirkwall, on Tuesday.

The Battle of Jutland in 1916 was crucial to the final victory by Britain and her allies two years later.

When the fleets of the British and German navies clashed on May 31, 1916, they kicked off the largest battle the Royal Navy has ever fought.

Overall more than 110,000 sailors in 150 British and 100 German vessels were involved.

A total of more than 6,000 British sailors and 2,500 Germans lost their lives.

The commemoration has been organised by the Department of Culture, Media and Sport.

Labour MPs have already warned Mr Corbyn against taking a break in the run up to the EU referendum vote.

But supporters say that even party leaders need a holiday occasionally.

Mr Corbyn warned of war's 'futility' after he laid his first Remembrance Sunday wreath as Labour leader last year.

But he faced accusations, hotly denied, that he did not bow deeply enough as he remembered the UK's war dead.
