Former MP George Galloway is due to make an announcement about whether he will stand in the by-election for Bradford West.
Mr Galloway posted on Facebook that he is visiting Bradford "for consultations about standing for parliament in the forthcoming by-election".
Last week, Mr Galloway Tweeted: "A by-election for the Parliamentary vacancy in Bradford West. Hmmm. Now THAT'S interesting ..."
It is not clear whether Mr Galloway would stand for Respect or as an independent in the poll, which is yet to have a formal date fixed. The by-election has been triggered because Labour backbencher Marsha Singh announced last week he is to step down as an MP following medical advice.
