• It’s another weekend of celebration in London with events including Trooping the Colour and the Hampton Court Palace Festival taking place. With Diamond Jubilee fever in the air, expect crowds for this year’s Trooping the Color – the annual celebration of the Queen’s birthday – held at Horse Guards Parade on Saturday. The procession down The Mall kicks off at 10am  with the flypast back at Buckingham Palace at 1pm (organisers advice getting your place by 9am – for more, follow this link). The Hampton Court Palace Festival, meanwhile, kicks off today with a performance by Liza Minnelli and runs through next week until John Barrowman performs at the festival’s closing next Saturday (24th June). The festival, set against the backdrop of Hampton Court Palace, this year celebrates its 20th year – among other performers are Van Morrison, James Morrison, Frankie Valli & The Four Seasons and this Saturday (16th June) sees the holding of the 20th Anniversary Classical Gala and fireworks.

• Park Lane’s central reservation is now hosting three new large scale sculptures by artist William Turnbull, considered a pioneer of modernism. The three works – 3×1 (1966), Large Horse (1990) and Large Blade Venus (1990) – have been installed as part of Westminster City Council’s ‘City of Sculpture’ festival. The works are on loan from the artist as well as the Yorkshire Sculpture Park and Chatsworth House, where they have been recently displayed.

• Professor Keith Simpson, a pathologist who has conducted post-mortems as part of the investigation into some of the country’s most infamous murders, has been honored with a green plaque at his former residence at 1 Weymouth Street by Wesminster City Council. The cases he worked on include the 1949 Acid Bath Murders (John George Haigh was hanged for the murder of six people in August that year) and the murder of gangster George Cornell, shot dead by Ronnie Kray in Whitechapel’s Blind Beggar Pub in 1966. Professor Simpson, who died in 1985, worked in the field of pathology for more than 30 years, taught at Guy’s Hospital in London and was renowned as having performed more autopsies than anyone else in the world.
