Sir - Next year I will be 60. As I intend to continue to work I will continue to use the bus to travel to work.

I would be interested to know how many other people who work after the age of 60 (by choice or necessity) are also being insulted by the Government's 'free' travel scheme.

I start work at 7.30am. At present, I use a monthly season ticket costing £59. After my 60th birthday I will be entitled to 'free' bus travel on any bus service - after 9.30am.

In order to travel to work then, I will need to buy a single ticket (at a cost of £3.50) each morning and return home on a free ticket. Effectively, this means that it will be more expensive to travel to work after I qualify for a 'free' pass.

If this is an example of Government mathematics, perhaps someone should suggest to them that the state pension is increased by, say, 200 per cent, so that we can afford their 'free' services.
