Sir, - In a column headed "Threat of a challenge to Trimble will not go away" (Opinion, June 1st), Mary Holland states that the "threat to Trimble's future comes from within his own community".
In an article in the Belfast Telegraph in 1968, Jack Sayers, the then editor, stated that "the threat to Northern Ireland's future is not from Mr Harold Wilson [prime minister, UK], or Mr Jack Lynch [Taoiseach], or the IRA, or nationalism. It comes from Protestant Ulstermen who will not allow themselves to be liberated from the delusion that every Roman Catholic is their enemy."
What, if anything, apart from over 3,000 dead, has changed in Unionist core values in Northern Ireland? - Yours, etc.,
