New Delhi, Mar 18 : In the run up to the Lok Sabha elections, Congress and the BJP are both suffering from a common ailment - losing trusted and tested allies.

While Lalu Prasad's RJD has given a jolt to Congress by allocating it only three seats in Bihar, Navin Patnaik's BJD has literally dumped BJP in Orissa and has virtually joined the fledgling Third Front.

With the Lok Sabha elections being likened to a "bowlers wicket" where no side can pile up a sizable score, the allies of both the Congress and BJP are fighting to "hog the bowling" by trying to grab as much political space as they can.

Since these allies are strong regional parties, they are wanting and ensuring that in their areas of influence, it is only their writ which runs and not that of the national parties.

In the key state of Uttar Pradesh, the UPA is as good as non-existent. The Congress's attempt to stitch up an alliance with the Samajwadi Party has floundered in the state, which with 80 seats, sends the largest number of members to the Lok Sabha.

The SP has declared candidates for 76 seats in the state, while the Congress has announced candidates for 24 seats so far. Congress leader Digvijay Singh indicated yesterday that there was little scope for any adjustment now.

The NDA is comparatively in a better situation in the Mayawati ruled state as the BJP has worked out an alliance with Ajit Singh's RLD although the saffron party's position has weakened considerably over a period of time with the Ayodhya issue gradually taking a backseat.

In Bihar, the Congress is licking its wounds inflicted by its allies and has threatened to contest as many seats as possible.

However, NDA is better placed in the Nitish Kumar-led state with JDU and BJP agreeing to fight 25 and 15 seats respectively. BJP, however, had to eat humble pie as it was forced to concede a seat to its alliance partner from the previously contested 16 seats.

What has come as a major setback to the NDA is Orissa where the Navin Patnaik led BJD, one of its oldest allies, walked out of the alliance on the eve of the polls, forcing the BJP to go it alone there.

Only neighbouring West Bengal provides a silver lining to the UPA as Congress has been able to thrash out a seat sharing formula with the Mamta Banerjee led Trinamool Congress.
