Rather than give Rolls-Royce a £1.25bn subsidy to develop the next-generation narrow-body jet airliner programme ( Nils Pratley on finance, 29 October ), would it not be more advantageous to the Treasury, and thus the taxpayer, me included, to invest £1.25bn in shares in the company? That way, we all get a share of the prospective profits, and in the long run pay lower taxes. Patrick Billingham Brighton, East Sussex

You say the Rothbury estate covers “an area the size of Athens” ( Wildlife Trusts hit £30m target to buy and rewild huge Northumberland estate, 30 October ).
