A vigil and die-in will be held in London this evening in memory of Moira Gemmill, the fifth cyclist to die on the roads of the capital this year.

Moira Gemmill, 55, died after being hit by a tipper truck at the notoriously hazardous junction of Lambeth Bridge and Millbank on April 9.

A leading light in Britain's design community, Ms Gemmill was renowned for her work as head of design at the Victoria and Albert Museum from 2002 to late 2014. She is credited with transforming the V&A to maake it feel, in the words of Mark Jones in The Guardian, "cared for and tended, light and airy, tranquil and engaging".

Ms Gemmill had recently been appointed director of capital programmes at the Royal Collections Trust, where she was to work on Windsor Castle, Buckingham Palace and Holyrood Palace in Edinburgh.

Five cyclists have been killed in collisions with motor vehicles in London this year. All five vehicles involved were HGVs and four were construction vehicles, leading to a call from Peter Murray, chairman of the New London Architecture forum, for architects to insist construction firms ensure that only lorries with properly trained drivers and the necessary safety equipment are employed on their sites.

Tonight's commemoration is being organised by the Stop Killing Cyclists advocacy group. Participants are asked to meet from 6pm for 6.30pm on Lambeth Bridge.

Stop Killing Cyclists said: "We ask as many of you as possible to attend and to remember our fellow cyclist as well as highlighting for the fifth time in just four months, the need for space and decent infrastructure for cyclists."
