Some parts of the different versions of the article were different.

All three said: "Growth cannot be ordered from the top down. It can only be nurtured from the bottom up."

In Scotland, Burnham wrote that meant "backing energy, shipbuilding, manufacturing and public services". In Wales this was "steel, ports, energy and manufacturing", and in London "housing, transport, skills and public services".

But many paragraphs are the same. Some sentences are the same in all three but have the names of places changed.

Both the London and Wales versions said: "Everyone can feel the country is not where it should be. People feel it in their bills, their rent, their high streets, their transport, and at the end of every month when there is less and less left over."

The WalesOnline Burnham article continued: "In Wales, that feeling has its own shape. It is felt in Merthyr. It is felt in Rhyl. Port Talbot feels it. It is felt in towns like Wrexham, communities like the Valleys, and places that have waited too long for politics to work for them."

The London version said: "In London, that feeling has its own shape. It is felt in Newham. It is felt in Brent. Croydon feels it. It is felt in towns like Barking, communities like Tottenham, and in places that have waited too long for politics to work for them."

All three said Burnham will set out a 10-year plan "to bring down the cost" of essentials, including "housing, energy and transport".

Housing policy in Wales is led by the Plaid Cymru government, as are roads, buses and some rail policy.

Burnham also promised to reform business rates in Scotland, London and Wales - business rates are set in Scotland and Wales by their respective devolved governments.
