Gordon Brown will be canvassing in his Scottish constituency after returning home to prepare for his first full week of General Election campaigning.
The Prime Minister flew back to Kirkcaldy in Fife on Friday night, telling Labour activists he would be fighting for "every vote" between now and May 6.
His campaigning has been relatively low-key so far, limited to the South East until Friday and focused mainly on intimate gatherings with small numbers of voters and Labour supporters.
On Friday night he was formally re-adopted as Labour's candidate for Kirkcaldy and Cowdenbeath, a safe seat where he was returned with an 18,216 majority in 2005.
He will be out and about in the constituency, knocking on doors and meeting the public. He is due to attend a community forum with pensioners in Cowdenbeath.
But after this weekend he will be touring the country in earnest, and must prepare for the first of the three-way televised leaders' debates that is to take place on Thursday. Tory leader David Cameron has been clocking up many more miles on the campaign trail.
At a meeting with constituency activists on Friday night, Mr Brown admitted he was not "slick" and could be too serious.
But, seeking to make a virtue of the contrasts drawn between himself and Mr Cameron, he vowed he would "fight and fight and fight".
"I have been accused of being too serious, too focused on policy and sometimes too impatient," he said, in a rare acknowledgement of some of the criticism he has attracted as a leader. I plead guilty. I am serious and focused and impatient, because when people's jobs and businesses and life savings are on the line, it's not a time for small talk. I realise I am not slick and the honest truth is I don't really want to be."
But he went on to say that he would never give up between now and polling day. He said: "So we go into this election fighting for causes as big as any we believed in in 1997. The ideals are as high, the aims as important, the chance of progress as great. And we will fight for every vote, in every seat, every hour between now and the close of polls. We fight with strength in our soul and confidence in our cause because we are the people's party - not simply a party in Britain, but the party of Britain."
