The following month, Gandhi's personal secretary Mahadev Desai wrote to Leighton, saying, "many of my friends who saw it [the oil portrait] in the Albany Gallery said to me that it was a good likeness".There doesn't seem to be any public record of the oil portrait being displayed elsewhere until 1978, when the Boston Public Library organised an exhibition of Leighton's works.

However, according to the artist's family, the portrait was thought to have been on display in the 1970s in the US, where it was allegedly damaged in a knife attack.A label attached to the backing board of the portrait says it was restored by the Lyman Allyn Museum Conservation Laboratory in Connecticut in 1974.The details of the alleged attack are not clear - according to Bonhams, it was carried out by a right-wing Hindu activist.

Hindu hardliners in India accuse Gandhi of having betrayed Hindus by being too pro-Muslim, and blame him for the division of India and the bloodshed that marked Partition, which saw India and Pakistan created after independence in 1947.He was shot dead on 30 January 1948 at a prayer meeting by Nathuram Godse, an activist with nationalist right-wing groups.

Three days on, and Ukraine is still digesting the full implications of Operation Spider's Web, Sunday's massive assault on Russia's strategic aviation.

On Wednesday, the agency which orchestrated the attack, the Security Service of Ukraine (SBU), released additional, vivid footage of the attacks in progress, as well as tantalising glimpses into how the whole complex operation was conducted.Earlier on Wednesday, the SBU offered a brief glimpse into another of Sunday's remarkable features: the use of specially constructed containers, mounted on flatbed trucks, to transport armed drones to sites close to the four Russian airbases.

Two videos show a truck carrying what appear to be two wooden mobile homes, complete with windows and doors.In one video, roof panels are clearly visible. Reports suggest these were retracted or otherwise removed shortly before the attacks began, allowing dozens of drones stored inside to take off.

It's not known when or where the videos were filmed, although snow visible beside the road in one suggests it could have been weeks or months ago.In another video, posted on a Russian Telegram channel on Sunday, a police officer was seen entering the back of one of the containers in the wake of the attack.
