SIR – Sex discrimination is illegal and I am pretty sure Linda Arnold (Letters, May 9) would not have it otherwise.

The age of retirement should be the same for both men and women, so why is she concerned about 500,000 women and not their male counterparts?

She says the delay is unnecessary, so she does not know the country is on its knees, financially, due to the last Administration, which also was going to raise the retirement ages.
