India had officially sent the invite to Trump in April this year.

US President Donald Trump has reportedly declined India's invitation to be the chief guest at the 2019 Republic Day parade.

According to India Today report, Trump's "domestic commitments", including his State of the Union address, around that time seem to have been the reason for declining the invitation.

This was conveyed in the form of a letter from US authorities to NSA Ajit Doval recently, the report said. In the letter, Trump is said to have regretted his inability to accept the invitation.

India had officially sent the Republic Day invite to the US president in April this year. The US authorities had confirmed receiving the invite, but said the final decision would be taken after the inaugural 2+2 dialogue in September. The Indian foreign ministry has not given a statement.
