Standing by the docks in downtown Nanaimo, B.C., on Monday morning, Liberal MP Alexandre Mendes told Radio-Canada she came to this week's Liberal caucus retreat with a message from her constituents: "dozens and dozens" of them were "adamant" the Liberal Party needed a new leader.

Speaking later to CBC's Power & Politics, Mendes said it was hard to pinpoint a specific reason or issue to explain her constituents' feelings for the prime minister.

"It's a very generalized ... 'we're tired of his face' kind of thing," she explained.
