During the recess, the Departmentally Related Standing Committees of Parliament examine the Demand for Grants submitted by various Ministries.  The Demand for Grants are detailed explanations of that Ministry's annual budget which form part of the total budget of the government.  These are examined in detail, and the committees can approve of the demands, or suggest changes.  The Demand for Grants are finally discussed and voted on by the Parliament after the recess.  (The post below lists the ministries whose Demand for Grants will be discussed in detail after the recess). The issue is - how effective is the institution of Parliament in examining the budget?  Though India specific information on this subject is hard to find, K. Barraclough and B. Dorotinsky have cited the World Bank - OECD Budget procedures Database to formulate a table on the legislature approving the budget presented by the executive ("The Role of the Legislature in the Budget Process: A Comparative Review", Legislative Oversight and Budgeting).  I reproduce the table below:

In Practice, does the legislature generally approve the budget as presented by the Executive? (in percent)
Answer All Countries OECD Countries Presidential democracies Parliamentary democracies
It generally approves the budget with no changes 34 33 14 41
Minor changes are made (affecting less than 3% of total spending) 63 67 71 59
Major changes are made (affecting more than 3% but less than 20% of total spending) 2 0 7 0
The budget approved is significantly different (affecting more than 20% of total spending) 0 0 0 0

The nominations for all phases of the General Election have been submitted.  We examine highlights from data on candidates who are participating in the ongoing elections.  There are 8,039 candidates contesting for 542 Parliamentary constituency seats.
 

On average, 14.8 candidates are contesting per constituency across the country.  Among all the states, Telangana has the highest average number of candidates contesting.  This is primarily due to 185 contestants from Nizamabad.  Excluding Nizamabad, the state’s average number of contestants would be 16.1.  

 

The Election Commission of India recognises parties as either national or state parties based on their performance in previous elections.  Delhi and Haryana have a high number of candidates contesting from parties that have not been recognised as either national or state parties.

After Telangana, Tamil Nadu has the highest average of independent candidates contesting in this election.  On average, of the candidates in each constituency in Tamil Nadu, two-thirds are contesting as independent candidates.  

 

After Nizamabad, the second highest number of candidate representation is seen in Belgaum, Karnataka.  The five constituencies that have the highest candidate representation are from the southern states of Telangana, Karnataka, and Tamil Nadu.    

 

The Bharatiya Janata Party and Congress are contesting 435 and 420 seats respectively.  In 373 seats they are in competition with each other.  BSP has the third highest number of candidates contesting in this election.

The seven national parties together fielded 2.69 candidates per constituency.  Among the largest five states, West Bengal has the highest representation of candidates from national parties, at 4.6.  In that state, candidates from five national parties are contesting.

Recognised state parties, together, fielded 1.53 candidates per constituency.  Bihar (6 state parties) and Tamil Nadu (8 state parties) see a high representation of candidates from state parties, at 1.2 and 1.3 respectively.

Largest states are ones with more than 30 Parliamentary constituency seats: Uttar Pradesh (80), Maharashtra (48), West Bengal (42), Bihar (40), and Tamil Nadu (39).  These states together have 249 seats i.e., 46% of Lok Sabha.

For these five states, the number of seats being contested by national and state parties is shown in the figures below.  

This analysis is based on the candidate list available on the Election Commission website (eci.gov.in) on May 8, 2019.
