Outspoken former St. Lucian government minister Sarah Flood-Beaubrun has resigned from the ruling Saint Lucia Labour Party (SLP).

Mrs Flood-Beaubrun hand delivered her letter of resignation to the SLP headquarters late on Wednesday.

The brief note to SLP Chairman - Tom Walcott said that the resignation takes effect immediately.

Mrs Flood Beaubrun was one of two women parliamentarians who won seats for the Labour Party in 1997 when it swept to power in general elections with a massive 16-1 majority.

In a subsequent election, Mrs Flood-Beaubrun retained her Castries Central seat, but fell out with Prime Minister Doctor Kenny Anthony and other ruling party colleagues when she publicly criticised a government bill to legalise abortion in special circumstances.

As a result of the criticism, Mr Anthony earlier this year fired the outspoken Mrs Flood-Beaubrun as Home Affairs Minister.

Her resignation as a member of the ruling party, will affect the government's majority in the house.
