Twitter users have sent goodwill and best wishes to Prince Philip after his planned retirement was announced today.
An emergency meeting called by the Queen caused mystery earlier this morning, with speculation as to why the "highly unusual" gathering had been called.
Eventually, Buckingham Palace announced the Prince Consort, the Duke of Edinburgh, would step down from public life in the autumn of 2017.
Since then, users on the social network have been wishing him well.
