HMS President (1918)
HMS President, formerly HMS Saxifrage is an Anchusa class corvette of the Royal Navy, completed in 1918. The vessel was built at the shipyard of Lobnitz & Company, Renfrew, Scotland as Yard Number 827 
She was originally named Saxifrage after the Saxifrage genus of plants which includes the variety London Pride, but was renamed President in July 1922 at the same time as she became a drill ship for the Royal Naval Volunteer Reserve. Currently, the name HMS President is given to a shore establishment of the Royal Naval Reserve near Tower Bridge.
It was purchased in April 2006 by the serviced office company, MLS Group Plc.
HMS President is permanently berthed in the River Thames on the Victoria Embankment in the City of London close to Blackfriars Millennium Pier and is listed on the National Register of Historic Vessels. It currently serves as a venue for conferences and functions and also houses the offices of a number of media companies. A notable event to have been hosted there was the 113th birthday celebrations of Henry Allingham, the world's oldest man and one of the last surviving the First World War veterans, in June 2009. He died the following month at his care home in East Sussex.
