Michael Landy's first major show for a while, and evidently the Goldsmiths' contemporary of Hirst et al has not lost his touch. Here he presents the offices and equipment of an invented cleaning company, its somewhat fascistic purpose to rid the world of "people who no longer play a useful role in society". A clever commentary on political correctness out of control.
Chisenhale Gallery, 64 Chisenhale Rd, London E3 (0181-981 4518). To 28 July
Out of the Fire
To coincide with the 80th anniversary, on 1 July, of the Battle of the Somme, in which some 19,000 soldiers died on the first day in the British army alone, an exhibition of First World War artists. All might be British, but you will be hard-pressed to find even the faintest hint of jingoism in this reflective and sobering show.
National Army Museum, Royal Hospital Rd, London SW1 (0171-730 0717). Thur to 14 July
Mountain Gloom, Mountain Glory
A look at the fixation with mountain scenery of British 19th-century Romantic artists. Turner is understandably prominent, but there are other important contributions from such contemporaries as Cozens, Palmer and de Wint.
Tate Gallery, Millbank, London SW1 (0171-887 8000). Today to 6 OctReuse content
