Congress President Sonia Gandhi has gone abroad for a routine check up and will not be in the country when results of the crucial assembly elections to five states come in on March 11.

According to Congress sources, Gandhi has gone abroad for routine a check up as advised by her doctors.

"She will be back after 3-4 days," said a party source.

In August last year, the Congress chief was taken ill during a road show in Varanasi, Prime Minister Narendra Modi's constituency.

Gandhi had on February 27 visited the Sir Ganga Ram Hospital (SRGH) here for a routine medical check up.

Earlier, Gandhi was twice admitted to the SRGH for her ill-health, during which she underwent a minor shoulder surgery.

Sonia Gandhi has not addressed any election campaign in Uttar Pradesh and instead issued appeal to voters through a statement and video.
