Nigel Farage has reportedly given Paul Nuttall six weeks to prove himself as UKIP gears up for the general election.
Nuttall has faced trying times since he was elected party leader. He has had to deal with internal struggles within UKIP as well as the fallout from a failed bid for election in Stoke.
Farage, the former party leader, said on Radio 4 he would continue to support the leader of UKIP, but he had six weeks to prove himself.
The MEP made it clear the general election would be a major test of his leadership.
Farage revealed he is considering whether he would stand for election in the June vote, saying he had to "weigh it up".
