Labour has urged the UK Government to publish a progress report on the implementation of the new Scottish rate of income tax.

The Scottish Parliament is due to take responsibility for 10p in the pound from Scottish pay packets from April and a confidential report into the progress of the tax power was handed to the UK Government in March.

Labour said the report concluded that successful delivery of the tax by April is merely "likely" and have questioned whether it is going to plan.

Shadow Scottish secretary Ian Murray has called on the UK and Scottish governments to publish the progress report, and "come clean about any problems we're going to face in a matter of months".

However, several parliamentary questions on the matter have been met with holding answers from the Scotland Office.

Mr Murray said: "In just over eight months the Scottish Parliament will take on the most tax powers it has ever had.

"Every person in Scotland will be affected as part of income tax is replaced by the new Scottish rate of income tax.

"Last year, Scottish Labour revealed that the UK and Scottish governments were not on track to identify every Scottish taxpayer, and then later in the year it emerged that the Scottish Government wanted to use NHS data to identify who should be liable for the new tax.

"Now the Government is blocking the publication of a detailed review of the project. They need to publish this report immediately.

"The new powers over income tax represent the biggest transfer of financial powers to the Scottish Parliament that has ever taken place.

"Instead of backroom meetings between the UK and Scottish governments, they need to come clean about any problems we're going to face in just a matter of months."
