HARROW East MP Tony McNulty has stepped down as minister for employment, welfare reform and London.
The Labour Parliamentarian had been embroiled in the expenses scandal and is being investigated by the Commissioner for Parliamentary Standards over whether mortgage reimbursements for his nominated second home in Wealdstone, in which his parents live, were legitimate.
A fortnight ago the former police minister revealed he had repaid £2,600 to the taxpayer for mortgage payment claims he had been overpaid and £455 in excess council tax.
Mr McNulty's departure from the Cabinet, followed a mass exodus of top ministers from the Government in three days surrounding yesterday's European and local elections.
Mr McNulty could not be contacted for explanation.
