The Parliamentary standards watchdog has launched an inquiry into claims that a Birmingham MP has failed to declare thousands of pounds in salary.
Jack Dromey (Lab Erdington) must answer to the Commons watchdog following accusations that he did not declare money he earned from his former job as a union official.
The inquiry will determine whether or not the MP has done anything wrong.
Mr Dromey, the Shadow Housing Minister, is a former Deputy General Secretary of Unite union.
He continued in that job until October 30 last year, five months after becoming an MP in May.
It has emerged that he received £27,867 from the union in that period, including salary and pay in lieu of notice.
But it was only this month that the money was registered on the official Register of Members’ Interests which all MPs are obliged to keep up to date.
Tory MP Andrew Bridgen has written to John Lyon, the Parliamentary Commissioner for Standards, this weekend asking him to investigate the matter.
They will determine whether Dromey made a “false or misleading registration of his financial interests”, and consider if a breach of the MPs’ code of conduct has occurred.
Mr Dromey said: “A Conservative MP has made accusations relating to my former employer, Unite the union.
“The Commissioner is perfectly properly investigating.
“I am co-operating fully with the investigation.”
For months, Mr Dromey’s entry in the register of Members’ interests read: “Deputy General Secretary of Unite Union... I am leaving this position and have declined my salary in the meantime.”
But it was updated on October 4 to read: “Deputy General Secretary of Unite Union...until 30 October 2010.
“Between the General Election and 30 October 2010, I received £27,867 in salary which included pay in lieu of notice.”
