This is despite the Election Commission's insistence the poll should be delayed till August.
 

But a spokesman said Mr Karzai might be prepared to compromise if an agreement could be reached on what should happen when his term of office ends in May.

The commission wants the delay for security and logistical reasons.

Interim
 

Mr Karzai's spokesman told the BBC that the president still wanted the poll in April.

But he said the president, parliament and the Supreme Court could agree to postpone the poll to August.

"If the issue goes to parliament and if the position of parliament changes and if the Supreme Court finds legal solutions, I think the president won't continue to insist that the elections take place in April."
 

One of the possible solutions could be the calling of a loya jirga - a meeting of tribal elders and leaders.

They would decide who would run the country after Mr Karzai's term of office ends in May.
 

Mr Karzai could also ask parliament to declare a state of emergency, allowing him to stay on as interim president.

Another possibility is the chairman of the upper house of parliament taking over the presidency temporarily.

The crisis was brought about after the Election Commission in January said the vote should be put back to August because the security situation and weather prevented a spring election.
 

Opponents of Mr Karzai said he should step down in May, but Mr Karzai said the elections should go ahead in April, in line with the constitution.
