London Zoo among names to sign petition calling on action from Rishi Sunak. / Breeding schemes for endangered animals such as rhinos and monkeys are being harmed by Brexit red tape - zoos have warned.

UK zoos have been warned that breeding schemes for bison, rhinos, monkeys and other endangered animals are being harmed by Brexit. Previously, about 1,400 animals a year were transferred between British aquariums or zoos and those in Europe but red tape meant that last year, the number fell to just over 200.

However, there are fears these breeding programmes designed to save critically endangered species could now be jeopardised by Brexit. / Zoos in Kent say they are being prevented from transferring animals because of red tape.

They will be joined by a young bull from Germany in mid-August, whose arrival was delayed by import complications related to Brexit.
