Charlie Maynard, the Liberal Democrat Treasury spokesperson, resigned on Friday in an attempt to unseat party leader Ed Davey, according to the Guardian.

Maynard's departure reflects months of frustration within the party over concerns that the Liberal Democrats are failing to connect with voters, the Guardian reports. The resignation signals a growing revolt against Davey's leadership as the party slips in polls.

The Guardian does not provide additional detail on other MPs involved in the reported dissent, the specific policy or strategic disagreements driving the discontent, or Davey's response to Maynard's departure.
