Conservative Party lawmaker Malcolm Rifkind has announced plans to leave Parliament after Britain's general election in May.

The senior party figure made the announcement Tuesday after he was linked to a lobbying scandal.

Rifkind and former foreign secretary Jack Straw from the Labour Party were caught in a hidden-camera sting that appeared to show each separately offering access to politicians and diplomats in exchange for fees.

Both have denied wrongdoing. Their cases are being reviewed.

Rifkind, a former foreign secretary, also is stepping down as chairman of the parliamentary committee that oversees the British intelligence service.

The undercover reporting by Channel 4's "Dispatches" program and the Daily Telegraph newspaper reopened a debate about political lobbying.
