April 23 (Reuters) - Tesla's revenue fell in the first quarter as it handed over fewer electric vehicles to customers due to slowing demand and intense competition worldwide.

The company on Tuesday reported revenue of $21.3 billion for the three months ended March, compared with $23.33 billion a year earlier. Analysts on average had estimated $22.15 billion, according to LSEG data.

The world's most valuable automaker recorded a fall in revenue in the second quarter of 2020, when the COVID-19 pandemic hampered production and deliveries.
