David Laws has faced a call to “stand aside” from his post as Chief Treasury Secretary after he admitted claiming expenses to pay rent to his partner.

Former Commissioner for Standards in Public Life Sir Alistair Graham said Mr Laws should remove himself while an investigation is carried out.

Mr Laws has apologised and said he will pay back the money which the Daily Telegraph said totalled £40,000.

The Lib Dem MP said he wanted to keep his relationship with the man private.
