LONDON, Feb 4 (Reuters) - Shareholders in Henderson Opportunities Trust HENT.L dealt a further blow to Saba Capital's campaign to shake-up Britain's 269 billion pound ($334 billion) investment trust sector on Tuesday, after rejecting the U.S. activist's proposals.

Investors in the trust rejected Saba's resolutions to remove several of its board members at a general meeting, with about 65% of votes cast against.

It joins fellow trusts Baillie Gifford US Growth USAB.L, Keystone Positive Change KPCK.L and Henderson Investment Trust HRI.L in blocking Saba's proposals.
