Ukraine says it has only a quarter of air defences needed to hold frontline

Also in the programme: ecologists in Costa Rica have just completed one of the largest ever surveys using audio recordings from its rainforests; and we talk to Ahmed Best who played the much-maligned character Jar Jar Binks in Star Wars' prequel films.

Julian Worricker is joined by British writer Timandra Harkness and economist Ganeshan Wignaraja.
