Saba Capital Management has added more UK investment trusts to its activist campaign and plans to further shake up the sector, the hedge fund's founder Boaz Weinstein told the LSE Alternative Investments Conference on Monday.

Saba Capital has requisitioned meetings at a further four investment trusts, with the US hedge fund aiming to convert each trust into open-ended funds.

Activist hedge fund manager Boaz Weinstein has kicked off a new campaign against four UK investment trusts following a failed attempt to gain control of some funds earlier.

Boaz Weinstein's firm Saba Capital announced that it will call meetings at the trusts to vote on whether to change their structure.
