The referendum parties

Sir: Zac Goldsmith and Sir John Major are each of them both right and wrong on the EU referendum (‘My dad saved Britain’, 28 February; Letters, 21 March). I was an MP interested in Europe, and then a PPS and minister on EU issues in the Foreign Office from 1997 to 2005, and it was pretty clear to all of us that Sir John’s decision to call a referendum on euro entry was motivated by his need to appease the rising Eurosceptic fronde in his party.
