STORY: Khan has been holding country-wide protests to push the government for early elections since being ousted from power in April. The protests were to culminate in a march to Islamabad, which threatened to worsen political turmoil in the nuclear-armed country which is battling an economic crisis.
"I have decided not to go to Islamabad because I know there will be havoc and the loss will be to the country," Khan said while speaking at a gathering of thousands of supporters in the garrison city of Rawalpindi, near the capital Islamabad.
Khan was earlier this month shot in the shin when his anti-government protest convoy bound for Islamabad came under attack in the east of the country, in what his aides said was a clear assassination attempt by his rivals.
He named Prime Minister Shehbaz Sharif and a senior military official of plotting his assassination, but both the government and military have denied involvement. Sharif has called for a transparent inquiry. One person has been arrested over the incident and said he acted alone.
