The prime minister's wife is to join Labour's campaign in the Glenrothes by-election this week, it has been revealed.
Sarah Brown will talk to voters in the Fife constituency ahead of the poll on 6 November.
She also plans to meet pensioners and young mothers during her day of campaigning in the town.
It comes a month after she took centre stage at the Labour conference to introduce her husband's keynote speech.
A spokesman for Scottish Labour confirmed that Mrs Brown intends to visit Glenrothes later in the week.
He said: "She will be coming at some point this week.
"She will be knocking on doors, meeting pensioners and also meeting young mums."
Prime Minister Gordon Brown last week confirmed in a letter to Labour MPs and peers that he intends to campaign in the constituency, which is next door to his own Kirkcaldy and Cowdenbeath seat.
Labour is defending a majority of 10,664 in a seat made vacant by the death of MP John MacDougall.
