Shareholders are set to vote on an £11bn merger between Standard Life and Aberdeen Asset Management.

The deal requires the backing of at least 75% of Aberdeen shareholders and 50% of Standard Life investors on Monday.

Analysts believe it will go ahead despite unease over the decision to have two chief executives and a 16 member board.

About 800 jobs from the companies' combined 9000-strong workforces would be cut over three years, saving about £200m annually.

David McCann, analyst at Numis Securities, said he believes the deal will be voted through by shareholders.

He said: "Future success in the active asset management industry will be determined by being big or small: you do not want to be stuck in the middle.

"We think the deal reflects Aberdeen and Standard Life choosing to be big."

The merger will make the combined group a top 20 player worldwide by assets under management, he added.

Eyebrows have also been raised over the proposed bonus structure that will see chief investment officer Rod Paris eligible to earn 865% of his £450,000 salary.
