Weight-loss jabs are “not the holy grail”, the NHS medical director has said. Prof Sir Stephen Powis said the drugs would be a “revolutionary” part of the approach that Britain takes to obesity.

The upcoming approval for the NHS to use another injection, called Mounjaro, dubbed by some as the King Kong of weight loss jabs for how well it appears works in trials, is expected to place even more pressure on the system, the report warns.

Health secretary Wes Streeting announced weight loss injections could be used to get people living with obesity "back to work" at full capacity.
