The official theme of this year's Venice Biennale is "In Minor Keys", but "The Law of Unintended Consequences" might be more apt.

It was plunged into chaos yesterday when the five international jury members announced their resignation.

They refused to explain their reasons instead referring readers back to an earlier statement saying they would not consider "those countries whose leaders are currently charged with crimes against humanity by the International Criminal Court" for the Golden Lion award.

That move, widely seen as critical of this year's inclusion of Russia and Israel, has now backfired with the biennale announcing two Visitors' Lions awards.

They will be voted for by the ticket-buying public with the award for "Best National Participation" open to all the countries on the official list raising the possibility of an Israeli or Russian win - the very thing the jury led by Brazilian curator Solange Oliveira Farkas did not want.

In the unlikely event of a Russian win, they will not be going to Latvia to celebrate - the Baltic state has just indefinitely banned three of its pavilion organizers, including Anastasia Karneeva and Yekaterina Vinokurova, from entering the country over their involvement in the event.

The biennale opens for previews on Wednesday.

The amount of money due to be handed out over the next decade to the five winners of the new Serpentine x FLAG Art Foundation Prize. A jury including Serpentine Galleries artistic director Hans Ulrich Obrist and Jon Rider, the director of the FLAG Art Foundation, met on April 23 to select the inaugural winner who will be announced on May 12.

It is all change (again) at the top of the Museum of Modern Art in Bogota (MAMBO), Colombia.

This time it is director Martha Ortiz who has resigned only months after the departure of artistic director Eugenio Viola.

Ortiz, who previously worked as a journalist, had only been in the job two years and The Art Newspaper reported she left "amid accusations of harassment and creating a toxic environment for her colleagues".

Viola does not seem sorry to see her go, telling the paper her departure was "necessary" and saying she needs to be replaced by "someone who understands that a museum is governed not by imposition but by dialogue, trust and ethical rigor”.

The National Gallery Singapore says it postponed a show about art in wartime due to "consideration for the uncertain global situation".

That message to subscribers did not give any further information on the decision to not go ahead with After The Monsoon: Art & War In Southeast Asia which was meant to open on May 22 and run to October 18.

A previous announcement about the show said it would examine how "art has been mobilised as a generative force for critically reflecting, remembering, documenting and healing in the face of conflict" and include work by Tuan Andrew Nguyen whose monumental Buddha was unveiled on New York's High Line this week.

Also among the work meant to feature was Sim Chi Yin's Interventions which feature her reinterpretation of archival photographs of the Malayan war from the collection of London's Imperial War Museum.

1 - Tate has appointed Daisy Desrosiers as their curator at large in North America. She is in charge of acquiring new North American work for the UK museums and succeeds Christine Y. Kim who was the first person in the role.

2 - The inaugural exhibitions at the Lucas Museum of Narrative Art in Los Angeles will include work by artists from Frank Frazetta to Rembrandt and Henri Cartier-Bresson. A YouTube video produced by the museum, run by Star Wars filmmaker George Lucas and his wife Mellody Hobson, said the shows would examine "universal themes like love, family, and adventure" when they open on September 22.

3 - The Studio Museum in New York's Harlem opens its latest show, Fade, today. It features work by 17 early-career American artists of African and Afro-Latinx descent and aims to reflect "the contemporary concerns of a new generation of artists".

4 - Two paintings by 18th-century Dutch master Jan van Huysum will be among the lots at Christie's Old Masters Evening Sale on June 30 in London. The works, both classic examples of his realistic paintings of flowers, are expected to sell for around $4 million each.
