Mark Menzies, a 52-year-old former Tory MP, has resigned from parliament and the Conservative party, citing personal pressures.

His resignation follows allegations of misusing campaign funds, which his former campaign manager claims the party failed to properly address.

The Conservative party's internal investigation identified improper behavior by Menzies but did not definitively conclude there was misuse of party funds.

Allegations have surfaced that Menzies used campaign funds to resolve a personal hostage situation, prompting Lancashire Police to review the matter.

If found in breach of the Nolan principles of public life, Menzies could face suspension from the Commons, as recommended by the Standards Commissioner.

The Conservative party has suspended Menzies from his role as a government trade envoy and has initiated retraining on campaign fund management.

Menzies will remain an MP on full salary until the next election and has asked for his family's privacy.

The ethical controversy surrounding Menzies adds to the Conservative party's challenges, following Boris Johnson's resignation amid his own ethical scandal.

The Labour Party has demanded a police investigation into Menzies' conduct as the country heads towards a general election.
