OTTAWA — A controversial Conservative senator has been expelled from his party’s caucus in the wake of a media report that he was having a sexual relationship with a 16−year−old girl.

An official in the Prime Minister’s Office says Sen. Don Meredith is no longer a member of the Tory caucus.

The Toronto Star is reporting that a woman claims she had a sexual relationship with Meredith that began shortly after she turned 16.

The Star says the woman, who is now 18, had sexually explicit online chats with Meredith and that the relationship progressed to kissing and touching before she turned 18.

She also says the pair had intercourse twice after she turned 18 before Meredith broke off the relationship earlier this year.

Meredith, who was appointed by Prime Minister Stephen Harper in 2010, did not immediately respond to calls and messages from The Canadian Press.

He was already the subject of a special review by the upper chamber as a result of a high level of staff turnover in his office.

A CTV News report earlier this month said Meredith is facing allegations from staff members of verbal abuse, sexual harassment and bullying, and has been subject to what the Senate calls a workplace assessment since February.
