Cable accentuates the coalition’s differences, but not without risk

The Liberal Democrats are in something of a purple patch at the moment, dominating aspects of government policy in the media. Last weekend, Danny Alexander broke his usually modest mould to stand square behind the 50p rate, in contrast to Boris Johnson and George Osborne. The debate encapsulates the current vogue for the coalition partners to accentuate their differences.

Today, enter Vince Cable pursued by a mansion tax. In an interview with the Telegraph, the Business Secretary concedes that the 50p rate is not a permanent fiscal instrument, but its removal (after 2015 when the income tax threshold has been raised to £10,000) will require a concession from the Conservatives. He said:

‘My party has always accepted that at some stage [the 50p rate] will have to be dealt with…[but]…if the top tax rate was removed it would need to be replaced with something else — primarily something associated with wealth or high value property.
