I enjoyed your article on discounts for the over-60s (Money hacks, 7 May), but there’s an even better National Trust discount than the one included. Any UK resident can join the National Trust for Scotland and get the same benefits, but cheaper. It has a joint senior membership that comes in at £99.60 annually, and does not require being a member for the previous three years. It’s valid across the UK.

• Peter Bottomley MP is right that the Electoral Commission recommended some form of voter ID (Letters, 6 May). But such restrictive forms of photo ID were not proposed. Millions of people do not have what is now required, and they do not need additional barriers to voting. The ID that can be used to collect a parcel at a post office (for example, a bank card or utility bill) or even the polling card issued to all voters should suffice.
