Following France in pension age maybe at the cost of votes 

France has been paralysed by strikes today as much of the country, as predicted, makes clear its unhappiness at President Emmanuel Macron's push to raise the state pension age from 62 to 64 years of age.
Mr Macron argues that the measure, which would save the French government an initial €17.7bn (£15.5bn) per year, is necessary because otherwise, due to the ageing population, the state pension will become unaffordable. The French president believes raising the state pension age is preferable to either cutting the state pension or retaining the status quo by either increasing government borrowing or putting up taxes. Events in France have prompted some to ask whether the pension age may also have to rise in the UK. The answer is that it already is.
 The pension age was set at 65 until November 2018, since then it has gradually risen to the current 66, which it hit in October 2020.
