A South London hospital's giant three-sided rainbow flag has been slammed by Health Secretary Steve Barclay's team as a 'virtue-signalling vanity project'. 

The Princess Royal University Hospital in Bromley launched a link bridge last week decorated with an 'intersex-inclusive flag' with the LGBT rainbow on it. 

The flag is the first mural of its kind on an NHS site and comes after months of criticism of what the Government branded 'waste and wokery'.

Senior executive at King's College Hospital NHS Foundation Trust, Jonathan Lofthouse, said it 'adorned the exterior of the link bridge with the Pride flag, a permanent installation celebrating diversity'.

However, according to The Telegraph, Health Secretary Mr Barclay did not agree with the move.

One source close to the minister said: 'This government is investing record funds in the NHS, including the £6.6billion extra over the next two years announced in the autumn statement. 

'Taxpayers want to see that cash used for cutting waiting lists and caring for patients, not wasted on virtue-signalling vanity projects.'

The 30-metre walkway, which took a year to build, was reportedly designed by intersex campaigner, Valentino Vecchietti.

The trust has not revealed how much the flag cost to make.
